Cleaning Up Files with the CLI
You can use the CLI request system storage cleanup command to rotate log files and delete unnecessary files on the device. If you are running low on storage space, the file cleanup procedure quickly identifies files that can be deleted.
The file cleanup procedure performs the following tasks:
- Rotates log files—Archives all information in the current log files, deletes old archives, and creates fresh log files.
- Deletes log files in /var/log—Deletes any files that are not currently being written to.
- Deletes temporary files in /var/tmp—Deletes any files that have not been accessed within two days.
- Deletes all crash files in /var/crash—Deletes any core files that the device has written during an error.
- Deletes all software images (*.tgz files) in /var/sw/pkg—Deletes any software images copied to this directory during software upgrades.
To rotate log files and delete unnecessary files with the CLI:
- Enter operational mode in the CLI.
- Rotate log files and identify the files that can be safely
deleted.user@host> request system storage cleanup
The device rotates log files and displays the files that you can delete.
- Enter yes at the prompt to delete the files.
