easily find megabyte eating files or directories

alias dush="du -sm *|sort -n|tail"

sorts the files by integer megabytes, which should be enough to (interactively) find the space wasters. Now you can dush for the above output, dush -n 3 for only the 3 biggest files and so on. It's always a good idea to have this line in your .profile or .bashrc

Sample Output

2       tools
4       kernel
6       firmware
14      Documentation
15      include
17      net
17      sound
28      fs

easily find megabyte eating files or directories

This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type): du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n (NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to: http://www.commandlinefu.com/commands/view/706/show-sorted-list-of-files-with-sizes-more-than-1mb-in-the-current-dir Show Sample Output

easily find megabyte eating files or directories

Thanks for the submit! My alternative produces summaries only for directories. The original post additionally lists all files in the current directory. Sometimes the files, they just clutter up the output. Once the big directory is located, *then* worry about which file(s) are consuming so much space.

Essentially the same as funky's alias, but will not traverse filesystems and has nicer formatting. Show Sample Output

You could add this in your profile with a different format to make it look less daunting:
$ alias dush="du -xsm * | \
              sort -n | \
              awk '{ \
                printf(\"%4s MB  ./\",\$1); \
                for ( i=1 ; i<=NF ; i++ ) { \
                  if ( i > 1 ) printf(\"%s \",\$i) \
                }; \
                printf(\"\n\") \
              }' | \
              tail"
```
