Bash filename autocompletion after switch/parameter

Question

I tried this other questions's accepted answer but it doesn't work for me. So please don't vote this as duplicate.

My script is named "tracker" and it accepts the following switches: --dummy --audit_sessiones --user_count --detailed_user_count --parfile

The --parfile switcj should be followed by a filename.

I have this autocompletion script:

_tracker() { local cur prev opts COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" prev="${COMP_WORDS[COMP_CWORD-1]}" opts="--dummy --audit_sessiones --user_count --detailed_user_count --parfile" if [[ ${cur} == -* ]] ; then COMPREPLY=( $(compgen -W "${opts}" -- ${cur}) ) return 0 fi opts="ls *" if [[ ${prev} == --parfile ]]; then COMPREPLY=( "${files[@]##*/}" ) return 0 fi } complete -F _tracker tracker

Autocompletion of switches works fine.

But I also want the user to be able to use filename autocompletion right after the parameter --parfile but I haven't been able to make it work.

complete has a -o default option so you can remove the opts="ls *"; if ... fi part and just do complete -F _tracker -o default tracker.

According to bash manual:

If the -o default option was supplied to complete when the compspec was defined, readline's default completion will be performed if the compspec (and, if attempted, the default bash completions) generate no matches.

Try replacing COMPREPLY=( "${files[@]##*/}" ) with COMPREPLY=( $(compgen -f ${cur}) )
