Check These Out

Sorted list of established destination connections
no need grep. its redundant when awk is present.

generate iso

HTTP GET request on wireshark remotly

Command to logout all the users in one command
This command logs out all users - which is way more secure to use ps -ef and "grep" to kill processes. Never ever use ps -ef piped to grep to kill something. If you ever need to ps-something use the UNIX95-directive, which makes sure you will never need "grep" together with "ps".

Another Matrix Style Implementation

Calculates the number of physical cores considering HyperThreading in AWK
Check whether hyperthreading is enabled or not. a better solution as nproc should work on all OS with awk

Quick notepad
Quick write some notes to a file with cat. Ctrl+C when you have finish.

Backup a remote database to your local filesystem
I have this on a daily cronjob to backup the commandlinefu.com database from NearlyFreeSpeech.net (awesome hosts by the way) to my local drive. Note that (on my Ubuntu system at least) you need to escape the % signs on the crontab.

Encryption file in commad line
This will encrypt your single file and create a filename.gpg file. Option: * -c : Encrypt with symmetric cipher To decrypt dhinesh@ubuntu:~$ gpg -c sample.rb.gpg

For a $FILE, extracts the path, filename, filename without extension and extension.
Useful for use in other scripts for renaming, testing for extensions, etc.
