I'd suggest the following. get-command add*group* Or for brevity gcm add*group* For reference, the Bash version is this: compgen -c | grep group Edit: Let's get crazier. You want custom tab completion to focus on the command's noun plus Bash style completion. $Function:OriginalTabCompletion = $Function:TabExpansion function TabExpansion($line, $lastWord) { if ($line -match ('^!(.*)') { $lastWord = $lastWord.trimstart('!') Get-command -noun *$lastWord* } elseif { OriginalTabExpansion $line $lastWord } } Set-psreadline -chord tab -function MenuComplete !group<TAB>
