Binary clock
Fun idea! This one adds seconds and keeps running on the same line. Perl's probably cheating though. :)

use xxd to create the wake on lan magicpacket and write to pcap file
just set macdst to the mac address of the system you wish to wake up, the macsrc is optional but helps use tcpreplay to broadcast or wireshark to view

Create a tar of directory structure only
The original suggestion did not work for me, when operating on folders located on an external mount (ie other than the root device) in Ubuntu. A variation using xargs does the trick.

Remove all subversion files from a project recursively
This command will remove all .svn folder from your project if you need to manual remove the subversion files.

bulk rename files with sed, one-liner
Far from my favorite, but works in sh and with an old sed that doesn't support '-E'

Find files recursively that were updated in the last hour ignoring SVN files and folders.
Find files recursively that were updated in the last hour ignoring SVN files and folders. Incase you do a full svn up on accident.

Show me just the ip address
Sometimes it's useful to output just the ip address. Or some other information, changing the "ipv4.addresses" in command. The power of awk! Show all possible "greps" with $ nmcli connection show [yourInterfaceNameHere]

list block devices
Shows all block devices in a tree with descruptions of what they are.

Indent a one-liner.
Bash builtin type also indents the function.

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)
