Subject: bash-completion: look for look completions
X-Git-Tag: v2.31-rc1~150
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=09ad914e72338da11b1b6a838f8dc9c210f98152;p=thirdparty%2Futil-linux.git

bash-completion: look for look completions

The look(1) uses positional arguments, where first one is a word from
dictionary.  It is reasonable to assume most of the time people search from
system word lists so propose completions from there.  The second argument is
a dictionary file, that might invalidate the first input but that only
happens to users who have an idea what the want without bash-completion.
