Remove cache and old extensions under "~/.vscode-server/" on your Linux server

README.md

If you often connect to your Linux server using VSCode, the "~/.vscode-server/" folder (and sometimes the ~/.cache/ folder too) can get very large because VSCode:

1. Does NOT clean its download cache after installing extensions;
2. Does NOT delete old extensions after updating them;
3. Does NOT remove old VSCode servers after installing a new version.

If your server storage space is limited, you might consider cleaning "~/.vscode-server/" (and ~/.cache/) regularly using the bash script I wrote. Simply run the following command:

curl -sL https://gist.githubusercontent.com/XDflight/5f3509eb84fc282b88059c909036f5bc/raw/b6b02d41c66c84d6332eb947c669dcd8973f393e/clean_vscode-server.sh | bash -s

This command will automatically download and run the script for you.

I programmed this thing because CMU only provides each student 2GB of AFS cloud storage in normal circumstances, unless maybe the courses you take requested for more, and since I often use VSCode to connect to Virtual Andrew via SSH to do homework, my "~/.vscode-server/" gets too big now and then that I have to clean it manually to keep my storage usage within the quota. This script automates the process to make my life easier.
