Question

Suppose I have:

alias gg="git grep"

then stuff like:

gg "int x"

works, but

gg int x

gets complaints. Is there a way to rewrite gg as a function in zsh so that it takes all the arguments after gg, and stuffs them into a string?

Thanks!

Answer 1

gg() { git grep "$*"; }

Answer 2

For your particular use case, this is a bad idea. git-grep is expecting a single-arg pattern. You re trying to get the shell to treat your space (between int and x) as part of the pattern. This will break quickly when you try something like: gg foo.*bar or various other things that the shell might interpret. So anything after gg really should be quoted. This is why git grep int x also doesn t work: fatal: ambiguous argument x : unknown revision or path not in the working tree...

If you think gg is a worthwhile keystroke saver, you should keep your arg to it consistent with what git-grep expects. Your original alias is fine for this. And continue to single- or double-quote your pattern, just like you do with any other regex-accepting command.
