I'm trying to setup autocompletion for a command, which takes only one parameter, a folder name,

In /secure/kernel_builds/, I have the three following subfolder:

3.5.6/ 3.6.2/ source/

Now I want auto completion, that lists all sub folder name possible, but not the one named source, right now I'm using a pretty stupid way to do it, by checking if the completion word is started with a number,

    case $COMP_CWORD in
            if [[ "${COMP_WORDS[COMP_CWORD]}" =~ ^[0-9] ]];then
                COMPREPLY=( /secure/kernel_builds/"${COMP_WORDS[COMP_CWORD]}"* )
                COMPREPLY=( /secure/kernel_builds/"${COMP_WORDS[COMP_CWORD]}"[0-9]*/ )
            COMPREPLY=( "${COMPREPLY[@]#/secure/kernel_builds/}" )
            COMPREPLY=( "${COMPREPLY[@]%/}" )

Is there a better way of doing so?

You can check in a loop for the strings you (don't) want:

declare -a accept
declare -a reject
for s in "${COMPREPLY[@]}"; do
    if [[ "$s" =~ want ]]; then
        accept=( "${accept[@]}" "$s" )
        reject=( "${reject[@]}" "$s" )
