New page

== Bash Completion ==

Hitting the tab to see available options can make life a lot easier. To add a new command to it you need to create the relevent file in /etc/bash_completion.d/ and then update the completions.

== Create a competion file for a command ==

Below is an example file for the command foo. It has to options show and configure. Each of these then have sub options.

<syntaxhighlight>
_foo()
{
local cur prev

cur=${COMP_WORDS[COMP_CWORD]}
prev=${COMP_WORDS[COMP_CWORD-1]}

case ${COMP_CWORD} in
1)
COMPREPLY=($(compgen -W "configure show" ${cur}))
;;
2)
case ${prev} in
configure)
COMPREPLY=($(compgen -W "CM DSP NPU" ${cur}))
;;
show)
COMPREPLY=($(compgen -W "some other args" ${cur}))
;;
esac
;;
*)
COMPREPLY=()
;;
esac
}

complete -F _foo foo
</syntaxhighlight>

== Source the completion file to update ==

<syntaxhighlight>
source /etc/bash_completion
</syntaxhighlight>
