Check These Out

See entire packet payload using tcpdump.

recursive search and replace old with new string, inside files
xargs deals badly with special characters (such as space, ' and "). To see the problem try this: touch important_file touch 'not important_file' ls not* | xargs rm Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

Recursive replace of directory and file names in the current directory.
This should work anywhere perl and grep is available. :P

Conficker Detection with NMAP

List dot-files and dirs, but not . or ..

Make directories for and mount all iso files in a folder

return external ip
I dont have curl or links installed, so I use wget with write file as standard out.

Auto-log commands
A quick alias I use right before logging into a server so that I have a log of the transactions as well as the ability to re-connect from another computer. Useful for when your boss says "what commands did you run again on that server?" and you had already closed the terminal ;) I wrapped it in a script now, with more features, but this is the heart of it. Never leave home without it.

Shows size of dirs and files, hidden or not, sorted.
Very useful when you need disk space. It calculates the disk usage of all files and dirs (descending them) located at the current directory (including hidden ones). Then sort puts them in order.

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.
