BASH: Print shell variable into AWK
Alternatively: export MyVAR=84; awk '{ print ENVIRON["MyVAR"] }'

Mac OS X - List all of my machine's IP addresses
On the Mac, the format ifconfig puts out is little different from Linux: the IP address is space separated, instead of colon. That makes parsing the IP address easier. See releated command for Linux/Unix: http://www.commandlinefu.com/commands/view/651/getting-the-ip-address-of-eth0

Create a backdoor on a machine to allow remote connection to bash
My netcat (nc-1.84-10.fc6) doesn't have the -e option, so I have to do it like this. Of course, instead of bash, you can use any executable, including scripts.

Getting ESP and EIP addresses from running processes
'ps' let you specify the format that you want to see on the output.

Install the Debian-packaged version of a Perl module
Running 'cpan Module::Name' will install that module from CPAN. This is a simple way of using a similar command to install a packaged Perl module from a Debian archive using apt-get.

Send command to all terminals in a screen session

Periodically run a command without hangups, and send the output to your e-mail
Run "ps -x" (process status) in the background every hour (in this example). The outputs of both "nohup" and "ps -x" are sent to the e-mail (instead of nohup.out and stdout and stderr). If you like it, replace "ps -x" by the command of your choice, replace 3600 (1 hour) by the period of your choice. You can run the command in the loop any time by killing the sleep process. For example $ ps -x 2925 ? S 0:00.00 sh -c unzip E.zip >/dev/null 2>&1 11288 ? O 0:00.00 unzip E.zip 25428 ? I 0:00.00 sleep 3600 14346 pts/42- I 0:00.01 bash -c while true; do ps -x | mail pascalv; sleep 3600; done 643 pts/66 Ss 0:00.03 -bash 14124 pts/66 O+ 0:00.00 ps -x $ kill 25428 You have mail in /mail/pascalv

Randomize lines in a file
This appends a random number as a first filed of all lines in SOMEFILE then sorts by the first column and finally cuts of the random numbers.

ShadyURL via CLI

Import SQL into MySQL with a progress meter
This uses PV to monitor the progress of the MySQL import and displays it though Zenity. You could also do this pv ~/database.sql | mysql -u root -pPASSWORD -D database_name and get a display in the CLI that looks like this 2.19MB 0:00:06 [ 160kB/s] [> ] 5% ETA 0:01:40 My Nautalus script using this command is here http://www.daniweb.com/forums/post1253285.html#post1253285
