du sh 文件大小

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
