How Linux views the file system (disk usage)

To view disk space remaining: df-th

Usage:df [Options] ... [File] ...

Displays the information for each < file > file system that is located, by default showing all file systems.

The parameters that must be used for the long option are also required when using the short option.

• -a,–all includes a file system of size 0 blocks
• -b,–block-size= size block to specify < size > bytes
• -h,–human-readable file system size in an easy-to-understand format (e.g. 1K 234M 2G)
• -h,–si is similar to-H but takes 1000 of the time instead of 1024
• -i,–inodes display Inode information rather than block usage
• -K is –block-size=1k
• -l,–local only show the native file system
• –no-sync No sync action (default) before getting usage data
• -p,–portability using the POSIX output format
• –sync sync action before getting usage data
• The-t,–type= type only prints the file system information for the specified < type >
• -t,–print-type Print File system type
• -x,–exclude-type= type only prints file system information that is not a specified < type >
• -V (this option is not processed)
