How to find size of particular directory on linux

du -sh file_path

Explanation

• du (disc usage) command estimates file_path space usage

• The options -sh are (from man du):

    -s, --summarize           display only a total for each argument      -h, --human-readable           print sizes in human readable format (e.g., 1K 234M 2G)  

  To check more than one directory and see the total, use du -sch:

    -c, --total           produce a grand total
