Sound Selector for MacOS

on MacOS, you can switch the input and output source on “system setting/sound”. i’d like todo this on the cli.

SwitchAudio

there is a litte tool called switchaudio. it can list, and also set the input/output device. let’s build a small wrapper around.

brew install switchaudio-osx

Git - Mass Updater

BASH, Script, Git

Intro

Let’s assume you have a bunch of GIT Repos in a Folder like this:

/project1/
    /repo1/
    /repo2/
    /repoN/

and you would like to update all of them ? here a little helper.

  • Loop over all Folders
  • check if ‘.git’ exists
  • if so, do a git pull –all

Script

Copy/Paste it to your Terminal and you get a executable Script called ‘git_update_all.sh’.

cat << 'EOF' > git_update_all.sh
#!/usr/bin/env bash

# Get the current script directory
script_dir=$(dirname "$(readlink -f "$0")")

# Change into each directory in the script folder
for dir in "$script_dir"/*; do

    if [ -d "$dir" ]; then

        cd "$dir" || exit 1

        if [ -d ".git" ]; then

            echo "Updating Git repository in $dir"
            git pull --all

        else

            echo "Skipping $dir - not a Git repository"

        fi

        cd "$script_dir" || exit 1

    fi

done

echo "Git update for all repositories completed."
EOF

# make it executable
chmod u+x git_update_all.sh

Usage

and then run it, like it, use it :)
