How to view free space on a Linux server

df -h

Explanation:

• df: This command stands for "disk free" and reports the amount of disk space used and available on Linux filesystems.
• -h: This option stands for "human-readable" format, which makes the output easier to read by showing sizes in KB, MB, GB, etc.

Sample Output:

When you run the df -h command, you might see output similar to the following:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        40G   25G   15G  63% /
udev            1.9G     0  1.9G   0% /dev
tmpfs           384M  1.2M  383M   1% /run
/dev/sda2       100G   50G   50G  50% /home

Additional Tips:

• Specific Filesystem: To view the space for a specific filesystem, add its path at the end of the command, like so:

  df -h /home

• Inodes: To check free inodes instead of disk space, use the -i option:

  df -i
