I created a detach script, being a wrapper around nohup:
#!/bin/bash /usr/bin/nohup "$@" &> /dev/null & and I want to get bash-completion to work for this script.
I try to use complete -c detach, but for all arguments there is an addition from the utilities from PATH.
How to properly implement bash-completion for my detach utility?
Since you are using bash-completion, the easiest solution is probably to ask it how nohup is completed1:
$ complete -p nohup complete -F _command nohup and then apply the same completion recipe to detach:
$ complete -F _command detach Refer to "Where should I install my own local completions?" in bash-completion's FAQ for the most suitable place for this command.
The _command function in turn invokes _command_offset, which is, according to a comment in bash_completion:
# A meta-command completion function for commands like sudo(8), which need to
# first complete on a command, then complete according to that command's own
# completion definition.
1 Assuming an interactive bash shell in which bash_completion has been sourced. If you are using Arch Linux, as a comment of yours seemed to suggest, this is true by default for every interactive Bash session (/etc/bash.bashrc sources /usr/share/bash-completion/bash_completion).
