Quick zsh script to update the multitude of git repositories I keep locally. Pretty brute force, but it works.

update_repos.sh

#!/usr/bin/env zsh

# Repository locations
REPOS=$HOME/src

# Keep our current directory on the stack
pushd

print -P "%F{green}=== %F{white}Pulling in the latest changes for all repositories in ${REPOS}..."

for i in $(find ${REPOS} -depth 2 -name ".git"); do
    print -P "\n%F{green}= %F{white} Repo: ${i%.git}"

    # Go to the .git parent directory to call the pull command
    cd ${i}
    cd ..

    # finally pull
    git pull origin
    if [ -f ".gitmodules" ]; then
        print -P "\n%F{green}= %F{white} Submodules for: ${i%.git}"
        git submodule update --remote
    fi
done

print -P "\n%F{green}=== Complete"

# Go back
popd

Added something to handle git submodules and not get tripped up by them.
