Script that lets you be very lazy when it comes to creating/reopening a project in VS Code.

codep.sh

#!/bin/sh

if [ "$#" -ne 1 ]; then
	cat <<- EOF
		Usage:	$0 PROJECT
		Creates the ~/workspace/PROJECT directory if it doesn't exist and opens it in VS Code.
	EOF
	exit 1
fi

mkdir -p ~/workspace/"$1"
code ~/workspace/"$1"

exit 1 tells the shell that something went wrong. This is useful for scripting, but some shells can be configured to look different when the last command exited with a non-zero exit-code. Additionally, [ is actually a command that exits 0 when the condition inside passes.
