Check These Out
You have a script where =ALL= STDERR should be redirected to STDIN and you don't want to add "2>&1" at the end of each command...
E.G.:
$ ls -al /foo/bar 2>&1
Than just add this piece of code at the beginning of your script!
I hope this can help someone. :)
Get your weather from a weather station just blocks from your home. Go to http://www.wunderground.com/wundermap/ and find a weather station near you. Click on a temperature bubble for that area. When the window pops up, click on hypertext link with the station ID, then on the bottom right of the page, click on the Current Conditions XML. Thats your link! Good luck!

sudo ipfw pipe 1 config bw 50KByte/s
Set the bandwidth (bw) limit to any number you want. For example you could have a 15kb pipe for X application and then a 100kb pipe for another application and attach things to those pipes. If a port isn’t attached to a pipe, it runs at full speed. Change the number (in this case 1) to a different number for a different pipe.
The next step is to attach your port.
sudo ipfw add 1 pipe 1 src-port 80
In this case anything on port 80 (http) will be set to a limit of 50Kbyte/s. If you want to attach a second port to this pipe, repeat the command but change the port number at the end.

This example uses xfreerdp, which builds upon the development of rdesktop. This example usage will also send you the remote machine's sound.
Use GNU/screen as a terminal emulator for anything serial console related.
screen /dev/tty
eg.
screen /dev/ttyS0 9600

Use this as a quick and simple alternative to the slightly verbose "du -s --max-depth=1"
Run as root. Path may vary depending on laptop model and video card (this was tested on an Acer laptop with ATI HD3200 video).
$ cat /proc/acpi/video/VGA/LCD/brightness
to discover the possible values for your display.
This command is a bit Linux specific, as --stdin doesn't exist for passwd on many Unix machines. Further, useradd is high level in most distributions and Unix derivatives except for the Debian family of distros, where adduser would be more appropriate. The last bit, with chage, will force the user to change their password on new login.
