7.2.2. The du command

Now that you know how much space has been used on a filesystem how can you find out where that data is? To view usage by a directory or file you can use du . Unless you specify a filename du will act recursively. For example:

   

user@server:~> du file.txt1300 file.txt
Or like the df I can use the -h and get the same output in "human-readable" form.

   

user@server:~> du -h file.txt1.3M file.txt


Unless you specify a filename du will act recursively.

   

user@server:~> du -h /usr/local4.0K /usr/local/games 16K /usr/local/include/nessus/net 180K /usr/local/include/nessus 208K /usr/local/include 62M /usr/local/lib/nessus/plugins/.desc 97M /usr/local/lib/nessus/plugins 164K /usr/local/lib/nessus/plugins_factory 97M /usr/local/lib/nessus 12K /usr/local/lib/pkgconfig 2.7M /usr/local/lib/ladspa 104M /usr/local/lib 112K /usr/local/man/man1 4.0K /usr/local/man/man2 4.0K /usr/local/man/man3 4.0K /usr/local/man/man4 16K /usr/local/man/man5 4.0K /usr/local/man/man
If you just want a summary of that directory you can use the -s option.

   

user@server:~> du -hs /usr/local210M /usr/local
