Programmable completion allows the user, while working in an interactive shell, to retrieve and auto-complete commands, their options, filenames, etc. Pressing [TAB] will complete on the current word, if only one match is found. If multiple completions are possible, they will be listed by hitting [TAB] again.

Requirements

The bash completion package version 2.0 or greater is recommended. https://github.com/scop/bash-completion If bash completion is present, and the version includes the _init_completion() function, completion on variables and redirection is available in addition. Otherwise option completion is fully supported, with the only exception, that object names with spaces are not working.

Installation

Quote from bash-completion README:

Install it in one of the directories pointed to by
bash-completion's pkgconfig file variables.  There are two
alternatives: the recommended one is 'completionsdir' (get it with
"pkg-config --variable=completionsdir bash-completion") from which
completions are loaded on demand based on invoked commands' names,
so be sure to name your completion file accordingly, and to include
for example symbolic links in case the file provides completions
for more than one command.  The other one which is present for
backwards compatibility reasons is 'compatdir' (get it with
"pkg-config --variable=compatdir bash-completion") from which files
are loaded when bash_completion is loaded.

For packages using GNU autotools the installation can be handled
for example like this in configure.ac:

 PKG_CHECK_VAR(bashcompdir, [bash-completion], [completionsdir], ,
   bashcompdir="${sysconfdir}/bash_completion.d")
 AC_SUBST(bashcompdir)

...accompanied by this in Makefile.am:

 bashcompdir = @bashcompdir@
 dist_bashcomp_DATA = # completion files go here

For cmake we ship the bash-completion-config.cmake and
bash-completion-config-version.cmake files. Example usage:

 find_package(bash-completion)
 if(BASH_COMPLETION_FOUND)
   message(STATUS
	 "Using bash completion dir ${BASH_COMPLETION_COMPLETIONSDIR}")
 else()
   set (BASH_COMPLETION_COMPLETIONSDIR "/etc/bash_completion.d")
   message (STATUS
	 "Using fallback bash completion dir ${BASH_COMPLETION_COMPLETIONSDIR}")
 endif()

 install(FILES your-completion-file DESTINATION
   ${BASH_COMPLETION_COMPLETIONSDIR})

For backwards compatibility it is still possible to put it into ~/.bash_completion or /etc/bash_completion.d/.

Tip: To make tab completion more handsome put the following into either /etc/inputrc or ~/.inputrc:

 set show-all-if-ambiguous on

This will allow single tab completion as opposed to requiring a double tab.

 set page-completions off

This turns off the use of the internal pager when returning long completion lists.
