Describe git projects

git-describe

#!/bin/bash

git-describe() {
    for dir in *; do
        [[ -d "$dir" ]] || continue
        [[ -d "$dir/.git" ]] || continue

        local branch="$(cd "$dir"; git rev-parse --abbrev-ref HEAD)"
        echo "$dir -> $branch"
    done
}

[[ "$0" == "$BASH_SOURCE" ]] && git-describe "$@"

Hi. Nice start. Some comments:

1. Use for dir in *; do -- no need for $(ls)
2. You can use || to join the conditions of the two if statements together and have just one if.

What's the point of the symbolic link?

Thanks @aharonscada!
I wrote that some time ago and didn't consider changing anything before publishing 😊

Now, regarding the symbolic link, I took a moment to think about your question.
At first, the point of the symbolic link was to be able to run ls -l and see all the directories and the branches they point to.
But, come to think of it, the command could've simply printed the output for you, thus resulting in a single bash command rather than two.

So thanks for all the suggestions! It's definitely much better now!

Glad to help. FYI, for the if what I had in mind was

if [[ ! -d "$dir" ]] || [[ ! d "$dir/.git" ]]
then
    continue
fi

Yeah I realized :) I prefer the shorter version where is very readable, so went with that...

We have different opinions about readability. But you're still young. :-) Take it easy --Aharon

As always, you are right 😉
