Answer / souravpoddar

There is no simple command available to find out the largest files/directories on a Linux/UNIX/BSD filesystem. However, combination of following three commands (using pipes) you can easily find out list of largest files:

du command : Estimate file space usage.
sort command : Sort lines of text files or given input data.
head command : Output the first part of files i.e. to display first 10 largest file.
find command : Search file.
Type the following command at the shell prompt to find out top 10 largest file/directories:
# du -a /var | sort -n -r | head -n 10

Sample outputs:

1008372 /var
313236 /var/www
253964 /var/log
192544 /var/lib
152628 /var/spool
152508 /var/spool/squid
136524 /var/spool/squid/00
95736 /var/log/mrtg.log
74688 /var/log/squid
62544 /var/cache

Answer / mayank
