Command
df -hT --exclude-type=tmpfs --exclude-type=devtmpfsWhen to use it
Use this as a first check when a Linux server can no longer write files, logs, or package updates.
How it works
- -h displays human-readable sizes.
- -T adds the filesystem type.
- Temporary filesystems are excluded to keep the output easier to read.
Precautions
- A full disk may require identifying the root cause before deleting anything.
Rollback
Read-only operation.
