A very simple command to toggle Chrome?s default style sheet. It uses the test command to see if the "Custom.css.off" file exists, if so, it will become "Custom.css", and if not, "Custom.css" is moved to "Custom.css.off" Thus, swapping.

This is accomplished with "&&" and "||"

The 'rename' command with the first argument as "'s/\.//'" and the second argument as "" will remove the specified extension from the filenames.

A simple bash function to the find command. I use this much more than find itself.

rename a network interface

e.g. make eth0 eth1 or vice versa

the interface needs to be down -> "/sbin/ifconfig oldname down"

Returns the most recently modified file in the current (or specified) directory. You can also get the oldest file, via:

ls -t1 $* | tail-1 ;

Realtime lines per second in a log file using python ... identical to perl version, except python is much better :)

chmod authorized_keys so you don't get "Authentication refused: bad ownership or modes for file /home/user/.ssh/authorized_keys"

Receives bzip'd tar archive via netcat (openbsd nc) and stores locally. Displays size with pv. Start this receiver first, then the sender.

Warning this will allow you to write to the system image on the phone, not recommended. But sometimes useful.

FQPN - Path = Filename

Remaining battery time is displayed in minutes

Iozone with a file of 2GB, 64KB record size, write/rewrite and read/re-read test, using just one thread.

Where ^M is entered by ctrl-v-m (v then m). Especially useful on cygwin when checking into a version control system. If you're not using all cygwin tools (e.g. strawberry perl instead of cygwin perl) you'll find yourself dealing with this constantly.

-U tells grep to process the file as binary; it needs this to work

-I ignores binary files so you won't get false positives

-l only prints the filename instead of the offending lines

-r recursive

On a machine behind a firewall, it's possible to pass the proxy server address in as a prefix to wget to avoid having to set it as an environment variable first.

This is especially useful to get crazy stuff like space characters copied to your pasteboard correctly.
