brename is a cross-platform command-line tool for safely batch renaming files/directories via regular expression.
-
Cross-platform. Supporting Windows, Mac OS X and Linux,
- Windows file systems, including NTFS and FAT, are case-insensitive.
Some operations are allowed on Linux, while they could be dangerous on Windows.
For example, renaming
test.tar.gztotest.tarwill overwriteTEST.tar.brename(v2.13.0 and later versions) can handle these cases appropriately (-wand-W).
- Windows file systems, including NTFS and FAT, are case-insensitive.
Some operations are allowed on Linux, while they could be dangerous on Windows.
For example, renaming
-
Safe. It helps you check potential conflicts and errors before it's too late.
Some common conflict and errors that might happen with commands like
mvorrename.New path existed: Existed files might be overwritten, causing data loss.Overwriting newly renamed path. Existed files might be overwritten, causing data loss. This case is hard to check by eyes.Missing target: New file is empty, that's not allowed.New path ending with a space: Not allowed in Windows. It's legal in Linux, but might cause unexpected errors.New path ending with a period: Not allowed in Windows.
-
Supporting dry run. A good habbit.
-
Supporting Undo the LAST successful operation, like a time machine.
-
Overwrite can be detected and users can choose whether overwrite or leave it (
-o/--overwrite-mode). -
File filtering.
- Supporting including (
-f/--include-filters) and excluding (-F/--exclude-filters) files via regular expression. - No need to run commands like
find ./ -name "*.html" -exec CMD.
- Supporting including (
-
Renaming submatch with corresponding value via key-value file (
-r "{kv}" -k kv.tsv). -
Renaming via ascending integer (
-r "{nr}"). -
Automatically making directoy: e.g., renaming
a-b-c.txttoa/b/c.txt. -
Recursively renaming both files and directories (
-R/--recursive,-D/--including-dir,--only-dir).
brename is implemented in Go programming language,
executable binary files for most popular operating systems are freely available
in release page.
Tip: run brename -V to check update !!!

Just download compressed
executable file of your operating system,
and decompress it with tar -zxvf *.tar.gz command or other tools.
And then:
-
For Linux-like systems
-
If you have root privilege simply copy it to
/usr/local/bin:sudo cp brename /usr/local/bin/ -
Or copy to anywhere in the environment variable
PATH:mkdir -p $HOME/bin/; cp brename $HOME/bin/
-
-
For windows, just copy
brename.exetoC:\WINDOWS\system32.
go get -u github.com/shenwei356/brename/

brename: a practical cross-platform command-line tool for safely batch renaming files/directories via regular expression
Version: 2.14.0
Author: Wei Shen <shenwei356@gmail.com>
Homepage: https://github.com/shenwei356/brename
Warnings:
1. The path in file systems like FAT32 or NTFS is case-insensitive, so you should switch on the flag
-w/--case-insensitive-path to correctly check file overwrites.
2. The flag -w/--case-insensitive-path is switched on by default on Windows, please use
-W/--case-sensitive-path to disable it if the file system is indeed case-sensitive.
3. New paths ending with periods of spaces, being error-prone, are not allowed.
Three path filters:
1. -S/--skip-filters black list default value: ^\. (skipping paths starting with ".")
2. -F/--exclude-filters black list no default value
3. -f/--include-filters white list default value: . (anything)
Notes:
1. Paths starting with "." are ignored by default, disable this with -S "".
2. These options support multiple values, e.g., -f ".html" -f ".htm".
But ATTENTION: each comma in filters is treated as a separator of multiple filters.
Please use double quotation marks for patterns containing comma, e.g., -p '"A{2,}"'
3. The three filters are performed in order of -S, -F, -f.
4. -F/--exclude-filters is prefered for excluding path, cause it has no default value.
Setting -S/--skip-filters will overwrite its default value.
Special replacement symbols:
{nr} Ascending integer
{kv} Corresponding value of the key (captured variable $n) by key-value file,
n can be specified by flag -I/--key-capt-idx (default: 1)
Special cases of replacement string:
*1. Capture variables should be in the format of '${1}' to reduce errors.
a). If the capture variable is followed with space or other simple, it's OK:
-r '$1 abc'
b). If followed by numbers, characters, or underscore. That is ambiguous:
-r '$1abc' actually refers to the variable '1abc', please use '${1}abc'.
-r '$2_$1' actually refers to the variable '2_', please use '${2}_${1}'.
2. Want to replace with a character '$',
a). If using '{kv}', you need use '$$$$' instead of a single '$':
-r '{kv}' -k <(sed 's/\$/$$$$/' kv.txt)
b). If not, use '$$'. e.g., adding '$' to all numbers:
-p '(\d+)' -d -r '$$${1}'
Usage:
brename [flags]
Examples:
1. dry run and showing potential dangerous operations (-d)
brename -p "abc" -d
2. dry run and only show operations that will cause error (-v)
brename -p "abc" -d -v 2
3. only renaming specific paths via include filters (-f)
brename -p ":" -r "-" -f ".htm$" -f ".html$"
4. renaming all .jpeg files to .jpg in all subdirectories (-R)
brename -p "\.jpeg" -r ".jpg" -R dir
5. using capture variables, e.g., $1, $2 ...
brename -p "(a)" -r "\$1\$1"
or brename -p "(a)" -r '$1$1' in Linux/Mac OS X
6. renaming directory too (-D)
brename -p ":" -r "-" -R -D pdf-dirs
7. using key-value file (-k)
brename -p "(.+)" -r "{kv}" -k kv.tsv
8. do not touch file extension (-e)
brename -p ".+" -r "{nr}" -f .mkv -f .mp4 -e
9. only list paths that match pattern (-l)
brename -i -f '.docx?$' -p . -R -l
10. undo the LAST successful operation (-u)
brename -u
11. disable undo if you do not want to create .brename_detail.txt (-x)
brename -p xxx -r yyy -x
12. clear/remove all .brename_detail.txt files (--clear)
brename --clear -R
13. also operate on hidden files: empty -S (default: ^\.)
brename -p xxx -r yyy -S ""
More examples: https://github.com/shenwei356/brename
Flags:
-w, --case-insensitive-path the file system (e.g., FAT32 or NTFS) is case-insensitive. It's
automatically swiched on on Windows
-W, --case-sensitive-path believing that the file system is case-sensitive. Please use this to
disable the flag -w/--case-insensitive-path, which is switched on by
default on Windows

-d, --dry-run print rename operations but do not run
-F, --exclude-filters strings exclude file filter(s) (regular expression, NOT wildcard). multiple

-K, --keep-key keep the key as value when no value found for the key
-I, --key-capt-idx int capture variable index of key (1-based) (default 1)

-a, --list-abs list absolute path, using along with -l/--list
-s, --list-sep string separator for list of found paths (default "\n")
--max-depth int maximum depth for recursive search (0 for no limit)
-N, --nature-sort list paths in nature sort, using along with -l/--list

to "001" by --nr-width 3 (default 1)
--only-dir only rename directories
-o, --overwrite-mode int overwrite mode (0 for reporting error, 1 for overwrite, 2 for not
renaming) (default 0)
-p, --pattern string search pattern (regular expression)
-q, --quiet be quiet, do not show any information and warning
-R, --recursive rename recursively
-r, --replacement string replacement. capture variables supported. e.g. $1 or ${1} (prefered)
represents the first submatch. ATTENTION: for *nix OS, use SINGLE
quote NOT double quotes or use the \ escape character. Ascending
integer is also supported by "{nr}"
-S, --skip-filters strings skip file filter(s) (regular expression, NOT wildcard). multiple
values supported, e.g., -S "^\." for skipping files starting with a
dot, but ATTENTION: each comma in the filter is treated as the
separator of multiple filters, please use double quotation marks for
patterns containing comma, e.g., -p '"A{2,}"' (default [^\.])
-n, --start-num int starting number when using {nr} in replacement (default 1)
-u, --undo undo the LAST successful operation
-v, --verbose int verbose level (0 for all, 1 for warning, error and renamed files, 2
for only error and renamed files) (default 2)
-V, --version print version information and check for update
