How to Manage Disk Space in SuperNinja

Last updated: April 30, 2026

The Linux Sandbox is a separate environment within SuperNinja where you can run scripts, test code, and perform tasks safely without affecting other parts of the system. It has an 8GB disk limit, so it’s important to occasionally clean up unnecessary files to ensure smooth operation. Here’s how you can check and free up space manually with the terminal.

 

1. Check Disk Usage

To see how much space you’re using:

df -h

  • h shows sizes in human-readable format (MB/GB).

  • Look for the line with your sandbox mount point (overlay).

 

2. Find Large Files

To find the largest files in your sandbox:

cd /workspace && du -ah | sort -rh | head -n 20

  • du -ah ~ lists all files and directories with sizes.

  • sort -rh sorts them by size, largest first.

  • head -n 20 shows the top 20 largest items.

3. Find Old Files

To find files older than 2 days, for example:

find ~ -type f -mtime +2 -ls | sort -k7

  • mtime +2 finds files modified more than 2 days ago.

  • Adjust the number to change the age.

4. Delete Unnecessary Files

Once you’ve identified files to remove:

rm /path/to/file

  • To delete a directory and everything inside:

rm -rf /path/to/directory

⚠ Be careful: Deleted files cannot be recovered. Only remove files you don’t need.
