Edit File: bash_completion.txt

Bash completion =============== Configuration files ------------------- *$BASH_COMPLETION_USER_FILE*:: Sourced late by bash_completion, pretty much after everything else. Use this file for example to load additional completions, and to remove and override ones installed by bash_completion. Defaults to `~/.bash_completion` if unset or null. *$XDG_CONFIG_HOME/bash_completion*:: Sourced by the bash_completion.sh profile.d script. This file is suitable for definitions of all `COMP_*` environment variables below. If `$XDG_CONFIG_HOME` is unset or null, `~/.config` is used instead of it. Environment variables --------------------- *BASH_COMPLETION_COMPAT_DIR*:: Directory for pre-dynamic loading era (pre-2.0) backwards compatibility completion files that are loaded eagerly from `bash_completion` when it is loaded. If unset or null, the default compatibility directory to use is `/etc/bash_completion.d`. *COMP_CONFIGURE_HINTS*:: 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. *COMP_CVS_REMOTE*:: 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. *COMP_FILEDIR_FALLBACK*:: 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. *COMP_IWLIST_SCAN*:: If set and not null, `iwconfig` completion will try to complete on available wireless networks identifiers. Default is unset. *COMP_KNOWN_HOSTS_WITH_HOSTFILE*:: 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. *COMP_KNOWN_HOSTS_WITH_AVAHI*:: 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. *COMP_TAR_INTERNAL_PATHS*:: If set and not null *before* sourcing bash_completion, `tar` completion will do correct path completion for tar file contents. If unset or null, `tar' completion will do correct completion for paths to tar files. See also README.
