The file and dir sizes of du -hs * is not consistent with du -hs

  • 772

When I run the bash command du -hs ., the output is

1.2G .

When I run the bash command du -hs *, the output is

If you add up all the file and dir size of the du -hs * output, it's about 600MB short of the du -hs . command. How do I figure out what's causing the 600MB? And why is there such a big discrepancy between the two commands?

    The du -hs * command will only report on files which will match that wildcard. That wildcard will not include any files or directories that begin with a period.

    The dh -sh command will check . (the current directory) so it will check everything under that directory, including any files beginning with a period.

    For example:

    $ du -shc *
2.0M    file.1
4.0M    file.2
5.9M    file.3
 12M    total

$ du -shc
 24M    .
 24M    total

$ ls -la 
total 48576

drwxr-xr-x  243 John  Bovi     8262 Aug 20 14:25 ..
-rw-r--r--    1 John  Bovi  2097152 Aug 20 14:26 .file.1
-rw-r--r--    1 John  Bovi  4145152 Aug 20 14:26 .file.2
-rw-r--r--    1 John  Bovi  6193152 Aug 20 14:26 .file.3
-rw-r--r--    1 John  Bovi  2097152 Aug 20 14:26 file.1
-rw-r--r--    1 John  Bovi  4145152 Aug 20 14:26 file.2
-rw-r--r--    1 John  Bovi  6193152 Aug 20 14:26 file.3

    An aside:

    To make things easier, instead of du -hs * use du -hsc *. It will provide a total so you don't have to add it up manually.
