List git branches in directory using bash with formatting

Question

I wants to list git branches in a set of directories using bash.

Now I just want to format the branch name differently if it's "master". In other words, if the branch is 'master' I want to display it in Blue or any other color.

Answer 1

There's no need to cd around for this. Just use something like this

reset=$(tput sgr0)
blue=$(tput setaf 4)
for dir in directory_name_1 directory_name_2 ...; do
    branch=$(GIT_DIR="$dir/.git" git symbolic-ref --short HEAD)

    color=
    if [ master = "$branch" ]; then
        color=$blue
    fi

    printf '%s: %s%s%s\n' "${dir##/*}" "$color" "$branch" "$reset"
done

Use tput to get the correct control codes for the current terminal for reset attributes ( sgr0 ) and for set foreground color ( setaf ) to blue (default color 4).
