Michal Privoznik b889594a70 tools: Set IFS for bash completion script ... The way our bash completion string is that is gets user's input and lets virsh completion code do all the work by calling 'virsh complete -- $INPUT". The 'complete' command is a "secret", unlisted command that exists solely for this purpose. After it has done it's part, it prints candidates onto stdout, each candidate on its own line, e.g. like this: # virsh complete -- "net-u" net-undefine net-update net-uuid These strings are then stored into a bash array $A like this: A=($($1 ${CMDLINE} complete -- "${INPUT[@]}" 2>/dev/null)) This array is then thrown back at bash completion to produce desired output. So far so good. Except, when there is an option with space. For instance: # virsh complete -- start --domain "" uefi\ duplicate uefi Bash interprets that as another array item because by default, Internal Field Separator (IFS) = set of characters that bash uses to split words at, is: space, TAB, newline. We don't want space nor TAB. Therefore, we have to set $IFS when storing 'virsh complete' output into the array. Thanks to Peter who suggested it.
