I have related but unsubmitted patches that I made before. I attach them. This adds a new flag option `-z` that makes the output of `compgen' separated by NUL This is useful when we want to process the candidates of compgen (that may contain newlines as a part of a candidate) using external commands such as `sort -z'. Also, now we can load a NUL-separated stream in an array by « mapfile -d '' ». Currently, there is no way to distinguish the newlines as a part of candidates from the newlines that are used to separate candidates. The option name `-z' could be alternatively `-0' or any other as far as it works. The first patch `r0034.compgen-update-desc.patch' update the description of existing options in manuals before adding the description of the new option. The patch `r0034.compgen-zflag.patch' adds the option -z. These are related discussions in bash-completion and ohmybash: https://github.com/scop/bash-completion/issues/704#issuecomment-1091631732 https://github.com/ohmybash/oh-my-bash/issues/341#issuecomment-1168073038 https://github.com/scop/bash-completion/pull/765#issuecomment-1173097965 I'd be glad if both `-z' and `-V' could be added in `compgen'. -- Koichi
