You mean "ls -lh /var > file.txt"?

This is the command script I use to find large directories:

06:54:24$ cat `type -p vss`
#!/bin/sh
find . -mount -type d -mindepth 1 -maxdepth 1 -exec du -s "{}" \;

It shows the largest dir immediately below (at a guess, that will be log in your case if you run in /var)
cd to that large directory and repeat.
When vss doesn't show the size you saw in the previous level, you're in the dir with big files. Use "ls -lSr" to show the largest files (small ones will scroll off the screen:)
If they're system log files, best cat /dev/null > them. After you've cleaned up the mess, implement file size limioting in your logrotate config file.

A simpler way do do the same (works on both files and dirs, unless hidden, like: /var/.name )

du -sc /var/* > file.txt
sort -nr file.txt | head -20 #show 20 largest files

cd to that large directory and repeat.
-c adds "total" disk space in the end of du output, which can help on subdirs

For ALL files and folders (errors ignored):
cd /var
du -sc * .[^.]* 2>/dev/null

Hi,

For cleaning your logs I would recommend editing the /etc/logrotate.conf file were you can have your logs compressed and
rotated daily, weekly, etc.

If you don't have logrotate then you can probably find it with your distro, and otherwise with:
it has a good description at:
