List top 10 files in filesystem or mount point bigger than 200MB
Specify the size in bytes using the 'c' option for the -size flag. The + sign reads as "bigger than". Then execute du on the list; sort in reverse mode and show the first 10 occurrences.

Smart `cd`.. cd to the file directory if you try to cd to a file
This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead. I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'.

Unlock more space form your hard drive
This command changes the reserved space for privileged process on '/dev/sda' to 1 per cent.

Replace spaces in filenames with underscores
I realize there's a few of these out there, but none exactly in this form, which seems the cleanest to me

infile search and replace on N files (including backup of the files)
the addition of ".bk" to the regular "pie" idiom makes perl create a backup of every file with the extension ".bk", in case it b0rks something and you want it back

send echo to socket network
this command will send a message to the socket 25 on host 192.168.1.2 in tcp. works on udp and icmp understand only IP address, not hostname. on the other side (192.168.1.2), you can listen to this socket and test if you receive the message. easy to diagnose a firewall problem or not.

Decode a MIME message
will decode a mime message. usefull when you receive some email and file attachment that cant be read.

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

show all programs connected or listening on a network port
Use the aliased command 'nsl'
