Checking Disk Usage on Linux
To check disk usage on a Linux system, you can use several commands depending on what information you need. Here are a few common commands:
1. Check Disk Usage of the Entire Filesystem
df -h
The df command reports file system disk space usage. The -h option makes the output human-readable, displaying sizes in KB, MB, or GB.
2. Check Disk Usage of a Specific Directory
du -sh /path/to/directory
The du command estimates file space usage. The -s option provides a summary of the disk usage for the directory. The -h option makes the output human-readable.
3. Check Disk Usage by Top Largest Files and Directories
du -ah /path/to/directory | sort -rh | head -n 10
This command lists the top 10 largest files and directories in the specified directory. The -a option includes files in the output, not just directories. The sort command sorts the output, and head limits the list to the top 10.
4. Check Inode Usage
df -i
The -i option with df shows inode usage, which is helpful if you are running out of inodes (the number of files) rather than disk space.
