This one-liner will output installed packages sorted by size in Kilobytes.

Show the top file size in human readable form

Show the top 10 file size

list top committers (and number of their commits) of svn repository.

in this example it counts revisions of current directory.

Also:

* find . -type f -exec ls -s {} \; | sort -n -r | head -5

* find . -type f -exec ls -l {} \; | awk '{print $5 "\t" $9}' | sort -n -r | head -5

Little faster alternative.

perl-less way

Alias to produce a list of all subdir sizes in current dir, in reverse order and human readable units. du is executed only once. Remove the slash after the asterisk to include files.

du -m option to not go across mounts (you usually want to run that command to find what to destroy in that partition)

-a option to also list . files

-k to display in kilobytes

sort -n to sort in numerical order, biggest files last

tail -10 to only display biggest 10

This command finds all of the functions defined in any shell script you specify including .bashrc

Directories listed in human-readable format

So your boss wants to know how much memory has been assigned to each virtual machine running on your server... here's how to nab that information from the command line while logged in to that server

This command allows you to find the effective uid and gid of the Apache process regardless of process name (which can be apache2 or httpd depending on distro).

emerge,apt-get,yum... all update your system. This will at some point replace either a runtime dependency or a process (which is still running).

This oneliner will list what processes need to be restarted

Your version works fine except for someone who's interested in commands 'sudo' was prefixed to

i.e. in your command, use of sudo appears as number of times sudo was used.

Slight variation in my command peeks into what commands sudo was used for and counts the command

(ignores 'sudo')
