OSX 中别名的制表符补全

Question

I have an alias to change the directory as given below.

test(){
cd /Users/newuser/test/sub1/sub2/$1
}

So when running test foldername , it will change the directory to a respective subdirectory in sub2 .

I used the below code for tab completion

_cdp () {
  … # code goes here
}
compdef _cdp cdp

as answered here Alias to cd into a subdirectory with completion . However, sourcing the profile triggered an error compdef not found.

NB: It is using a bash shell, not zsh.

How can I implement a tab completion for the alias so that, if a Tab is done after the alias, it will list the possible folders

Answer 1

compdef is a zsh command only. For bash use complete .

You can use programmable completion as in your example, where you specify a function (here _cdp ) that generates the possible completions by adding them to the array COMPREPLY+=(some new entries) . Often, these entries are generated by compgen .

complete -F _cdp cdp

But in this case there is an easier option: Specify the possible completions directly using

IFS=$'\n' complete -W "$(cd /Users/newuser/test/sub1/sub2/ && compgen -G '*/')" cdp
