Sourced late by bash_completion, pretty much after everything else.
Use this file for example to load additional completions, and to remove
and override ones installed by bash_completion. Defaults to
~/.bash_completion if unset or null.
Available since version 2.7.
Sourced by the bash_completion.sh profile.d script. This file is
suitable for definitions of all COMP* shell variables below.
If $XDG_CONFIG_HOME is unset or null,~/.config is
used instead of it.
Available since version 1.90.
Directory for pre-dynamic loading era (pre-2.0) and other backwards
compatibility completion files that are loaded eagerly from bash_completion
when it is loaded. If unset or null, the default compatibility directories to
use are /etc/bash_completion.d, and bash_completion.d relative to
bash_completion location.
Available since version 1.1.
If set and not null, completions that look for filenames based on their "extensions" will fall back to suggesting all files if there are none matching the sought ones.
Available since version 2.12.
Deprecated alias: COMP_FILEDIR_FALLBACK
If set and not null, known hosts completion will try to use avahi-browse
for additional completions. This may be a slow operation in some setups.
Default is unset.
Available since version 2.12.
Deprecated alias: COMP_KNOWN_HOSTS_WITH_AVAHI
If set and not null (default), known hosts completion will complement
hostnames from ssh's known_hosts files with hostnames taken from the file
specified by the HOSTFILE shell variable (compgen -A hostname). If null,
known hosts completion will omit hostnames from HOSTFILE. Omitting
hostnames from HOSTFILE is useful if HOSTFILE contains many entries for
local web development or ad-blocking.
Available since version 2.12.
Deprecated alias: COMP_KNOWN_HOSTS_WITH_HOSTFILE
Files in BASH_COMPLETION_COMPAT_DIR (the compat dir) to ignore, specified by
a glob pattern. The completion files in the compat dir whose basename matches
with this pattern will not be sourced by bash_completion at its load time.
This variable can be used to suppress the problematic completions. Note that
backup files and Makefiles in the compat dir are by default ignored regardless
of this setting.
One example is acroread.sh which is installed by some versions of Adobe
Reader, overrides _filedir with an incompatible version, and causes
various problems. To recover this _filedir, another completion file
redefine_filedir had been placed in the compat dir, which could also
cause another incompatibility when the user uses their own version of
bash-completion instead of the systemwide version. To suppress these files
one can set the following value:
export BASH_COMPLETION_COMPAT_IGNORE='@(acroread.sh|redefine_filedir)'- https://bugzilla.redhat.com/677446

If set and not null, configure completion will return the entire option
string (e.g. --this-option=DESCRIPTION) so one can see what kind of data
is required and then simply delete the descriptive text and add one's own
data. If unset or null (default), configure completion will strip
everything after the = when returning completions.
Available since version 2.12.
Deprecated alias: COMP_CONFIGURE_HINTS
If set and not null, cvs commit completion will try to complete on
remotely checked-out files. This requires passwordless access to the
remote repository. Default is unset.
Available since version 2.12.
Deprecated alias: COMP_CVS_REMOTE
If set and not null, iwconfig completion will try to complete on
available wireless networks identifiers. Default is unset.
Available since version 2.12.
Deprecated alias: COMP_IWLIST_SCAN
If set and not null, various samba related tool completions perform a network scan to complete domains and hosts. Default is unset.
Available since version 2.12.
Deprecated alias: COMP_SAMBA_SCAN
If set and not null before sourcing the tar completion, it will do
correct path completion for tar file contents. If unset or null,
paths to tar files will be correctly completed. Unfortunately we do not
have a way to make both Just Work properly at the moment. We consider it
more important to have proper completion of paths to tar files than it is
to have completion for their contents, so the default is unset.
Available since version 2.12.
Deprecated alias: COMP_TAR_INTERNAL_PATHS
If on, completions producing command names do not do anything if the command to be completed is empty. This can be useful on systems where generating the entire list of commands takes a long time.
Available since version 2.12.
