How can I fix typing a command name twice in zsh?

Question

So I have this (bad) habit of typing git , pausing for a sec to glance at the output of the git status command I just typed, then typing git add ... afterwards, resulting in the rather unsuccessful git git add ....

Is there any functionality of zsh that would allow me to always replace git git with its singular equivalent?

Answer 1

I can't edit comments, so here is a working version for all bourne shells:

git(){ if [ "$1" = git ]; then shift; fi; command git "$@"; }

Answer 2

One way would be with a wrapper function:

function git { if [[ $1 == "git" ]]; then shift; fi; /path/to/git $@; }

This discards the second "git" if it's present and runs git with the parameters requested. This should work in zsh, Bash and ksh.
