2. Starting With Netrw *netrw-start* {{{1
Netrw makes reading files, writing files, browsing over a network, and
local browsing easy! First, make sure that you have plugins enabled, so
you'll need to have at least the following in your <.vimrc>:
(or see |netrw-activate|) >
set nocp " 'compatible' is not set
filetype plugin on " plugins are enabled
<
(see |'cp'| and |:filetype-plugin-on|)
Netrw supports "transparent" editing of files on other machines using urls
(see |netrw-transparent|). As an example of this, let's assume you have an
account on some other machine; if you can use scp, try: >
vim scp://hostname/path/to/file
<
Want to make ssh/scp easier to use? Check out |netrw-ssh-hack|!
So, what if you have ftp, not ssh/scp? That's easy, too; try >
vim ftp://hostname/path/to/file
<
Want to make ftp simpler to use? See if your ftp supports a file called
<.netrc> -- typically it goes in your home directory, has read/write
permissions for only the user to read (ie. not group, world, other, etc),
and has lines resembling >
machine HOSTNAME login USERID password "PASSWORD"
machine HOSTNAME login USERID password "PASSWORD"
...
default login USERID password "PASSWORD"
<
Now about browsing -- when you just want to look around before editing a
file. For browsing on your current host, just "edit" a directory: >
vim .
vim /home/userid/path
<
For browsing on a remote host, "edit" a directory (but make sure that
the directory name is followed by a "/"): >
vim scp://hostname/
vim ftp://hostname/path/to/dir/
<
See |netrw-browse| for more!
There are more protocols supported by netrw than just scp and ftp, too: see the
next section, |netrw-externapp|, on how to use these external applications with
netrw and vim.
PREVENTING LOADING *netrw-noload*
If you want to use plugins, but for some reason don't wish to use netrw, then
you need to avoid loading both the plugin and the autoload portions of netrw.
You may do so by placing the following two lines in your <.vimrc>: >
:let g:loaded_netrw = 1
:let g:loaded_netrwPlugin = 1

3. Netrw Reference *netrw-ref* {{{1
Netrw supports several protocols in addition to scp and ftp as mentioned
in |netrw-start|. These include dav, fetch, http,... well, just look
at the list in |netrw-externapp|. Each protocol is associated with a
variable which holds the default command supporting that protocol.
EXTERNAL APPLICATIONS AND PROTOCOLS *netrw-externapp* {{{2
Protocol Variable Default Value
-------- ---------------- -------------
dav: *g:netrw_dav_cmd* = "cadaver" if cadaver is executable
dav: g:netrw_dav_cmd = "curl -o" elseif curl is available
fetch: *g:netrw_fetch_cmd* = "fetch -o" if fetch is available
ftp: *g:netrw_ftp_cmd* = "ftp"
http: *g:netrw_http_cmd* = "elinks" if elinks is available
http: g:netrw_http_cmd = "links" elseif links is available
http: g:netrw_http_cmd = "curl" elseif curl is available
http: g:netrw_http_cmd = "wget" elseif wget is available
http: g:netrw_http_cmd = "fetch" elseif fetch is available
rcp: *g:netrw_rcp_cmd* = "rcp"
rsync: *g:netrw_rsync_cmd* = "rsync -a"
scp: *g:netrw_scp_cmd* = "scp -q"
sftp: *g:netrw_sftp_cmd* = "sftp"
*g:netrw_http_xcmd* : the option string for http://... protocols are
specified via this variable and may be independently overridden. By
default, the option arguments for the http-handling commands are: >
elinks : "-source >"
links : "-source >"
curl : "-o"
wget : "-q -O"
fetch : "-o"
<
For example, if your system has elinks, and you'd rather see the
page using an attempt at rendering the text, you may wish to have >
let g:netrw_http_xcmd= "-dump >"
< in your .vimrc.
READING *netrw-read* *netrw-nread* {{{2
Generally, one may just use the url notation with a normal editing
command, such as >
:e ftp://[user@]machine/path
<
Netrw also provides the Nread command:
:Nread ? give help
:Nread "machine:path" uses rcp
:Nread "machine path" uses ftp w/ <.netrc>
:Nread "machine id password path" uses ftp
:Nread "dav://machine[:port]/path" uses cadaver
:Nread "fetch://[user@]machine/path" uses fetch
:Nread "ftp://[user@]machine[[:#]port]/path" uses ftp w/ <.netrc>
:Nread "http://[user@]machine/path" uses http uses wget
:Nread "rcp://[user@]machine/path" uses rcp
:Nread "rsync://[user@]machine[:port]/path" uses rsync
:Nread "scp://[user@]machine[[:#]port]/path" uses scp
:Nread "sftp://[user@]machine/path" uses sftp
WRITING *netrw-write* *netrw-nwrite* {{{2
One may just use the url notation with a normal file writing
command, such as >
:w ftp://[user@]machine/path
<
Netrw also provides the Nwrite command:
:Nwrite ? give help
:Nwrite "machine:path" uses rcp
:Nwrite "machine path" uses ftp w/ <.netrc>
:Nwrite "machine id password path" uses ftp
:Nwrite "dav://machine[:port]/path" uses cadaver
:Nwrite "ftp://[user@]machine[[:#]port]/path" uses ftp w/ <.netrc>
:Nwrite "rcp://[user@]machine/path" uses rcp
:Nwrite "rsync://[user@]machine[:port]/path" uses rsync
:Nwrite "scp://[user@]machine[[:#]port]/path" uses scp
:Nwrite "sftp://[user@]machine/path" uses sftp
http: not supported!
SOURCING *netrw-source* {{{2
One may just use the url notation with the normal file sourcing
command, such as >
:so ftp://[user@]machine/path
<
Netrw also provides the Nsource command:
:Nsource ? give help
:Nsource "dav://machine[:port]/path" uses cadaver
:Nsource "fetch://[user@]machine/path" uses fetch
:Nsource "ftp://[user@]machine[[:#]port]/path" uses ftp w/ <.netrc>
:Nsource "http://[user@]machine/path" uses http uses wget
:Nsource "rcp://[user@]machine/path" uses rcp
:Nsource "rsync://[user@]machine[:port]/path" uses rsync
:Nsource "scp://[user@]machine[[:#]port]/path" uses scp
:Nsource "sftp://[user@]machine/path" uses sftp
DIRECTORY LISTING *netrw-dirlist* {{{2
One may browse a directory to get a listing by simply attempting to
edit the directory: >
:e scp://[user]@hostname/path/
:e ftp://[user]@hostname/path/
<
For remote directories (ie. those using scp or ftp), that trailing
"/" is necessary (the slash tells netrw to treat the argument as a
directory to browse instead of a file to download).
However, the Nread command can also be used to accomplish this:
:Nread [protocol]://[user]@hostname/path/
*netrw-login* *netrw-password*
CHANGING USERID AND PASSWORD *netrw-chgup* *netrw-userpass* {{{2
Attempts to use ftp will prompt you for a user-id and a password.
These will be saved in global variables g:netrw_uid and
s:netrw_passwd; subsequent uses of ftp will re-use those two items to
simplify the further use of ftp. However, if you need to use a
different user id and/or password, you'll want to call NetUserPass()
first. To work around the need to enter passwords, check if your ftp
supports a <.netrc> file in your home directory. Also see
|netrw-passwd| (and if you're using ssh/scp hoping to figure out how
to not need to use passwords, look at |netrw-ssh-hack|).
:NetUserPass [uid [password]] -- prompts as needed
:call NetUserPass() -- prompts for uid and password
:call NetUserPass("uid") -- prompts for password
:call NetUserPass("uid","password") -- sets global uid and password
NETRW VARIABLES AND SETTINGS *netrw-variables* {{{2
(also see: |netrw-browser-var| |netrw-protocol| |netrw-settings| |netrw-var|)
Netrw provides a lot of variables which allow you to customize netrw to your
preferences. One way to look at them is via the command :NetrwSettings (see
|netrw-settings|) which will display your current netrw settings. Most such
settings are described below, in |netrw-browser-options|, and in
|netrw-externapp|:
*b:netrw_lastfile* last file Network-read/written retained on a
per-buffer basis (supports plain :Nw )
*g:netrw_chgwin* specifies a window number where file edits will take
place. (also see |netrw-C|)
(default) not defined
*g:Netrw_funcref* specifies a function to be called when netrw edits
a file. The file is first edited, and then the
function reference (|Funcref|) is called.
(default) not defined
*g:netrw_ftp* if it doesn't exist, use default ftp
=0 use default ftp (uid password)
=1 use alternate ftp method (user uid password)
If you're having trouble with ftp, try changing the
value of this variable to see if the alternate ftp
method works for your setup.
*g:netrw_ftpextracmd* default: doesn't exist
If this variable exists, then any string it contains
will be placed into the commands set to your ftp
client. As an example:
="passive"
*g:netrw_ftpmode* ="binary" (default)
="ascii"
*g:netrw_ignorenetrc* =0 (default for linux, cygwin)
=1 If you have a <.netrc> file but it doesn't work and
you want it ignored, then set this variable as
shown. (default for Windows + cmd.exe)
*g:netrw_menu* =0 disable netrw's menu
=1 (default) netrw's menu enabled
*g:netrw_nogx* if this variable exists, then the "gx" map will not
be available (see |netrw-gx|)
*g:netrw_uid* (ftp) user-id, retained on a per-vim-session basis
*s:netrw_passwd* (ftp) password, retained on a per-vim-session basis
*g:netrw_preview* =0 (default) preview window shown in a horizontally
split window
=1 preview window shown in a vertically split window.
Also affects the "previous window" (see |netrw-P|) in
the same way.
*g:netrw_scpport* = "-P" : option to use to set port for scp
*g:netrw_sshport* = "-p" : option to use to set port for ssh
*g:netrw_sepchr* =\0xff
=\0x01 for enc == euc-jp (and perhaps it should be for
others, too, please let me
know)
Separates priority codes from filenames internally.
See |netrw-p12|.
*g:netrw_silent* =0 : transfers done normally
=1 : transfers done silently
*g:netrw_use_errorwindow* =1 : messages from netrw will use a separate one
line window. This window provides reliable
delivery of messages. (default)
=0 : messages from netrw will use echoerr ;
messages don't always seem to show up this
way, but one doesn't have to quit the window.
*g:netrw_win95ftp* =1 if using Win95, will remove four trailing blank
lines that o/s's ftp "provides" on transfers
=0 force normal ftp behavior (no trailing line removal)
*g:netrw_cygwin* =1 assume scp under windows is from cygwin. Also
permits network browsing to use ls with time and
size sorting (default if windows)
=0 assume Windows' scp accepts windows-style paths
Network browsing uses dir instead of ls
This option is ignored if you're using unix
*g:netrw_use_nt_rcp* =0 don't use the rcp of WinNT, Win2000 and WinXP
=1 use WinNT's rcp in binary mode (default)
PATHS *netrw-path* {{{2
Paths to files are generally user-directory relative for most protocols.
It is possible that some protocol will make paths relative to some
associated directory, however.
>
example: vim scp://user@host/somefile
example: vim scp://user@host/subdir1/subdir2/somefile
<
where "somefile" is in the "user"'s home directory. If you wish to get a
file using root-relative paths, use the full path:
>
example: vim scp://user@host//somefile
example: vim scp://user@host//subdir1/subdir2/somefile
<
==============================================================================
4. Network-Oriented File Transfer *netrw-xfer* {{{1
Network-oriented file transfer under Vim is implemented by a VimL-based script
(<netrw.vim>) using plugin techniques. It currently supports both reading and
writing across networks using rcp, scp, ftp or ftp+<.netrc>, scp, fetch,
dav/cadaver, rsync, or sftp.
http is currently supported read-only via use of wget or fetch.
<netrw.vim> is a standard plugin which acts as glue between Vim and the
various file transfer programs. It uses autocommand events (BufReadCmd,
FileReadCmd, BufWriteCmd) to intercept reads/writes with url-like filenames. >
ex. vim ftp://hostname/path/to/file
<
The characters preceding the colon specify the protocol to use; in the
example, it's ftp. The <netrw.vim> script then formulates a command or a
series of commands (typically ftp) which it issues to an external program
(ftp, scp, etc) which does the actual file transfer/protocol. Files are read
from/written to a temporary file (under Unix/Linux, /tmp/...) which the
<netrw.vim> script will clean up.
Now, a word about Jan Minář's "FTP User Name and Password Disclosure"; first,
ftp is not a secure protocol. User names and passwords are transmitted "in
the clear" over the internet; any snooper tool can pick these up; this is not
a netrw thing, this is a ftp thing. If you're concerned about this, please
try to use scp or sftp instead.
Netrw re-uses the user id and password during the same vim session and so long
as the remote hostname remains the same.
Jan seems to be a bit confused about how netrw handles ftp; normally multiple
commands are performed in a "ftp session", and he seems to feel that the
uid/password should only be retained over one ftp session. However, netrw
does every ftp operation in a separate "ftp session"; so remembering the
uid/password for just one "ftp session" would be the same as not remembering
the uid/password at all. IMHO this would rapidly grow tiresome as one
browsed remote directories, for example.
On the other hand, thanks go to Jan M. for pointing out the many
vulnerabilities that netrw (and vim itself) had had in handling "crafted"
filenames. The |shellescape()| and |fnameescape()| functions were written in
response by Bram Moolenaar to handle these sort of problems, and netrw has
been modified to use them. Still, my advice is, if the "filename" looks like
a vim command that you aren't comfortable with having executed, don't open it.
*netrw-putty* *netrw-pscp* *netrw-psftp*
One may modify any protocol's implementing external application by setting a
variable (ex. scp uses the variable g:netrw_scp_cmd, which is defaulted to
"scp -q"). As an example, consider using PuTTY: >
let g:netrw_scp_cmd = '"c:\Program Files\PuTTY\pscp.exe" -q -batch'
let g:netrw_sftp_cmd= '"c:\Program Files\PuTTY\psftp.exe"'
<
See |netrw-p8| for more about putty, pscp, psftp, etc.
Ftp, an old protocol, seems to be blessed by numerous implementations.
Unfortunately, some implementations are noisy (ie., add junk to the end of the
file). Thus, concerned users may decide to write a NetReadFixup() function
that will clean up after reading with their ftp. Some Unix systems (ie.,
FreeBSD) provide a utility called "fetch" which uses the ftp protocol but is
not noisy and more convenient, actually, for <netrw.vim> to use.
Consequently, if "fetch" is available (ie. executable), it may be preferable
to use it for ftp://... based transfers.
For rcp, scp, sftp, and http, one may use network-oriented file transfers
transparently; ie.
>
vim rcp://[user@]machine/path
vim scp://[user@]machine/path
<
If your ftp supports <.netrc>, then it too can be transparently used
if the needed triad of machine name, user id, and password are present in
that file. Your ftp must be able to use the <.netrc> file on its own, however.
>
vim ftp://[user@]machine[[:#]portnumber]/path
<
However, ftp will often need to query the user for the userid and password.
The latter will be done "silently"; ie. asterisks will show up instead of
the actually-typed-in password. Netrw will retain the userid and password
for subsequent read/writes from the most recent transfer so subsequent
transfers (read/write) to or from that machine will take place without
additional prompting.

+=================================+============================+============+
(*1) For an absolute path use scp://machine//path.
(*2) if <.netrc> is present, it is assumed that it will
work with your ftp client. Otherwise the script will
prompt for user-id and password.
(*3) for ftp, "machine" may be machine#port or machine:port
if a different port is needed than the standard ftp port
(*4) for http:..., if wget is available it will be used. Otherwise,
if fetch is available it will be used.
Both the :Nread and the :Nwrite ex-commands can accept multiple filenames.
NETRC *netrw-netrc*
The <.netrc> file, typically located in your home directory, contains lines
therein which map a hostname (machine name) to the user id and password you
prefer to use with it.
The typical syntax for lines in a <.netrc> file is given as shown below.
Ftp under Unix usually supports <.netrc>; ftp under Windows usually doesn't.
>
machine {full machine name} login {user-id} password "{password}"
default login {user-id} password "{password}"
Your ftp client must handle the use of <.netrc> on its own, but if the
<.netrc> file exists, an ftp transfer will not ask for the user-id or
password.
Note:
Since this file contains passwords, make very sure nobody else can
read this file! Most programs will refuse to use a .netrc that is
readable for others. Don't forget that the system administrator can
still read the file! Ie. for Linux/Unix: chmod 600 .netrc
PASSWORD *netrw-passwd*
The script attempts to get passwords for ftp invisibly using |inputsecret()|,
a built-in Vim function. See |netrw-uidpass| for how to change the password
after one has set it.
Unfortunately there doesn't appear to be a way for netrw to feed a password to
scp. Thus every transfer via scp will require re-entry of the password.
However, |netrw-ssh-hack| can help with this problem.
==============================================================================
5. Activation *netrw-activate* {{{1
Network-oriented file transfers are available by default whenever Vim's
|'nocompatible'| mode is enabled. Netrw's script files reside in your
system's plugin, autoload, and syntax directories; just the
plugin/netrwPlugin.vim script is sourced automatically whenever you bring up
vim. The main script in autoload/netrw.vim is only loaded when you actually
use netrw. I suggest that, at a minimum, you have at least the following in
your <.vimrc> customization file: >
set nocp
if version >= 600
filetype plugin indent on
endif
<
==============================================================================
6. Transparent File Editing *netrw-transparent* {{{1
Transparent file transfers occur whenever a regular file read or write
(invoked via an |:autocmd| for |BufReadCmd|, |BufWriteCmd|, or |SourceCmd|
events) is made. Thus one may read, write, or source files across networks
just as easily as if they were local files! >
vim ftp://[user@]machine/path
...
:wq
See |netrw-activate| for more on how to encourage your vim to use plugins
such as netrw.
==============================================================================
7. Ex Commands *netrw-ex* {{{1
The usual read/write commands are supported. There are also a few
additional commands available. Often you won't need to use Nwrite or
Nread as shown in |netrw-transparent| (ie. simply use >
:e url
:r url
:w url
instead, as appropriate) -- see |netrw-urls|. In the explanations
below, a {netfile} is an url to a remote file.
*:Nwrite* *:Nw*
:[range]Nw[rite] Write the specified lines to the current
file as specified in b:netrw_lastfile.
(related: |netrw-nwrite|)
:[range]Nw[rite] {netfile} [{netfile}]...
Write the specified lines to the {netfile}.
*:Nread* *:Nr*
:Nr[ead] Read the lines from the file specified in b:netrw_lastfile
into the current buffer. (related: |netrw-nread|)
:Nr[ead] {netfile} {netfile}...
Read the {netfile} after the current line.
*:Nsource* *:Ns*
:Ns[ource] {netfile}
Source the {netfile}.
To start up vim using a remote .vimrc, one may use
the following (all on one line) (tnx to Antoine Mechelynck) >
vim -u NORC -N
--cmd "runtime plugin/netrwPlugin.vim"
--cmd "source scp://HOSTNAME/.vimrc"
< (related: |netrw-source|)
:call NetUserPass() *NetUserPass()*
If g:netrw_uid and s:netrw_passwd don't exist,
this function will query the user for them.
(related: |netrw-userpass|)
:call NetUserPass("userid")
This call will set the g:netrw_uid and, if
the password doesn't exist, will query the user for it.
(related: |netrw-userpass|)
:call NetUserPass("userid","passwd")
This call will set both the g:netrw_uid and s:netrw_passwd.
The user-id and password are used by ftp transfers. One may
effectively remove the user-id and password by using empty
strings (ie. "").
(related: |netrw-userpass|)
:NetrwSettings This command is described in |netrw-settings| -- used to
display netrw settings and change netrw behavior.
==============================================================================
8. Variables and Options *netrw-options* *netrw-var* {{{1
(if you're interested in the netrw browser settings, see: |netrw-browser-var|)
The <netrw.vim> script provides several variables which act as options to
affect <netrw.vim>'s file transfer behavior. These variables typically may be
set in the user's <.vimrc> file: (see also |netrw-settings| |netrw-protocol|)
>
-------------

g:netrw_rcp_cmd variable ="rcp"
g:netrw_rsync_cmd variable ="rsync -a"
g:netrw_scp_cmd variable ="scp -q"
g:netrw_sftp_cmd variable ="sftp" >
-------------------------------------------------------------------------
<
*netrw-ftp*
The g:netrw_..._cmd options (|g:netrw_ftp_cmd| and |g:netrw_sftp_cmd|)
specify the external program to use handle the ftp protocol. They may
include command line options (such as -p for passive mode).
Browsing is supported by using the |g:netrw_list_cmd|; the substring
"HOSTNAME" will be changed via substitution with whatever the current request
is for a hostname.
Two options (|g:netrw_ftp| and |netrw-fixup|) both help with certain ftp's
that give trouble . In order to best understand how to use these options if
ftp is giving you troubles, a bit of discussion is provided on how netrw does
ftp reads.
For ftp, netrw typically builds up lines of one of the following formats in a
temporary file:
>
IF g:netrw_ftp !exists or is not 1 IF g:netrw_ftp exists and is 1
---------------------------------- ------------------------------
<
open machine [port] open machine [port]
user userid password userid password
[g:netrw_ftpmode] password
[g:netrw_extracmd] [g:netrw_ftpmode]
get filename tempfile [g:netrw_extracmd]
get filename tempfile >
---------------------------------------------------------------------
<
The |g:netrw_ftpmode| and |g:netrw_extracmd| are optional.
Netrw then executes the lines above by use of a filter:
>
:%! {g:netrw_ftp_cmd} -i [-n]
<
where
g:netrw_ftp_cmd is usually "ftp",
-i tells ftp not to be interactive
-n means don't use netrc and is used for Method #3 (ftp w/o <.netrc>)
If <.netrc> exists it will be used to avoid having to query the user for
userid and password. The transferred file is put into a temporary file.
The temporary file is then read into the main editing session window that
requested it and the temporary file deleted.
If your ftp doesn't accept the "user" command and immediately just demands a
userid, then try putting "let netrw_ftp=1" in your <.vimrc>.
*netrw-cadaver*
To handle the SSL certificate dialog for untrusted servers, one may pull
down the certificate and place it into /usr/ssl/cert.pem. This operation
renders the server treatment as "trusted".
*netrw-fixup* *netreadfixup*
If your ftp for whatever reason generates unwanted lines (such as AUTH
messages) you may write a NetReadFixup() function:
>
function! NetReadFixup(method,line1,line2)
" a:line1: first new line in current file
" a:line2: last new line in current file
if a:method == 1 "rcp
elseif a:method == 2 "ftp + <.netrc>
elseif a:method == 3 "ftp + machine,uid,password,filename
elseif a:method == 4 "scp
elseif a:method == 5 "http/wget
elseif a:method == 6 "dav/cadaver
elseif a:method == 7 "rsync
elseif a:method == 8 "fetch
elseif a:method == 9 "sftp
else " complain
endif
endfunction
>
The NetReadFixup() function will be called if it exists and thus allows you to
customize your reading process. As a further example, <netrw.vim> contains
just such a function to handle Windows 95 ftp. For whatever reason, Windows
95's ftp dumps four blank lines at the end of a transfer, and so it is
desirable to automate their removal. Here's some code taken from <netrw.vim>
itself:
>
if has("win95") && g:netrw_win95ftp
fun! NetReadFixup(method, line1, line2)
if method == 3 " ftp (no <.netrc>)
let fourblanklines= line2 - 3
silent fourblanklines.",".line2."g/^\s*/d"
endif
endfunction
endif

INTRODUCTION TO BROWSING *netrw-intro-browse* {{{2
(Quick References: |netrw-quickmaps| |netrw-quickcoms|)
Netrw supports the browsing of directories on your local system and on remote
hosts; browsing includes listing files and directories, entering directories,
editing files therein, deleting files/directories, making new directories,
moving (renaming) files and directories, copying files and directories, etc.
One may mark files and execute any system command on them! The Netrw browser
generally implements the previous explorer's maps and commands for remote
directories, although details (such as pertinent global variable names)
necessarily differ. To browse a directory, simply "edit" it! >
vim /your/directory/
vim .
vim c:\your\directory\
<
(Related topics: |netrw-cr| |netrw-o| |netrw-p| |netrw-P| |netrw-t|
|netrw-mf| |netrw-mx| |netrw-D| |netrw-R| |netrw-v| )
The Netrw remote file and directory browser handles two protocols: ssh and
ftp. The protocol in the url, if it is ftp, will cause netrw also to use ftp
in its remote browsing. Specifying any other protocol will cause it to be
used for file transfers; but the ssh protocol will be used to do remote
browsing.
To use Netrw's remote directory browser, simply attempt to read a "file" with
a trailing slash and it will be interpreted as a request to list a directory:
>
vim [protocol]://[user@]hostname/path/
<
where [protocol] is typically scp or ftp. As an example, try: >
vim ftp://ftp.home.vim.org/pub/vim/
<
For local directories, the trailing slash is not required. Again, because it's
easy to miss: to browse remote directories, the url must terminate with a
slash!
If you'd like to avoid entering the password repeatedly for remote directory
listings with ssh or scp, see |netrw-ssh-hack|. To avoid password entry with
ftp, see |netrw-netrc| (if your ftp supports it).
There are several things you can do to affect the browser's display of files:
* To change the listing style, press the "i" key (|netrw-i|).
Currently there are four styles: thin, long, wide, and tree.
To make that change "permanent", see |g:netrw_liststyle|.
* To hide files (don't want to see those xyz~ files anymore?) see
|netrw-ctrl-h|.
* Press s to sort files by name, time, or size.
See |netrw-browse-cmds| for all the things you can do with netrw!
*netrw-getftype* *netrw-filigree* *netrw-ftype*
The |getftype()| function is used to append a bit of filigree to indicate
filetype to locally listed files:
directory : /
executable : *
fifo : |
links : @
sockets : =
The filigree also affects the |g:netrw_sort_sequence|.
