Sorting Files By Size

In case anybody was wondering, I'm still alive. I've been inordinately busy lately and have been spending the majority of my free time online re-learning Ruby on Rails. I've also been digging into multi-master and circular replication schemes for MySQL and MySQL proxy. I plan on sharing some of the things I've learned sometime in the near future. Anyway, here's a handy tip that I just used this morning.

If you want to sort all the files in a directory by size, you can do the following:

ls -lsR | sort -nr

The sort command will order by the number of blocks in each file. The biggest files are at the top.

I just use 'ls -rS' here. No?

I often do:

$ ls -l | sort -k5,5 -n

As Steve writes, the -S option is the key. These are all good:

ls -S
ls -sS
ls -lS

They give just the filenames, just file size and name, and the full long listing respectively, with the biggest file at the top.

I often combine it with head:

ls -lS | head
ls -lS | head -20
