Objective: Print the lyrics for the current playing song.
How: We'll create a small bash
script to do the fetching for us (using curl
) and then we'll
display it either in the terminal or in our $EDITOR
First we'll need to get the name of the current song and its artist:
# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer! | |
export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ " | |
# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty! | |
# ~/code/web:beta_directory$ git checkout master | |
# Switched to branch "master" | |
# ~/code/web:master$ git checkout beta_directory | |
# Switched to branch "beta_directory" |
