Bash completion
===============
Environment variables
---------------------
*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_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.
