List alive hosts in specific subnet
Works on any machine with nmap installed. Previous version does not work on machines without "seq". Also works on subnets of any size.

underscore to camelcase

Copy files to a remote host with SFTP with a leading dot, then rename them to the real file name
Usage: $ sftp-cp * | sftp user@host:/dir This is useful if there is a process on the remote machine waiting for files in an incoming directory. This way it won't see half-transmitted files if it ignores hidden files.

Script Terminal Session
script -f /tmp/foo will place all output of the terminal, including carriage returns, to a file. This file can be tail dash-eff'ed by one or more other terminals to display the information of the main terminal. Good way to share one's screen on short notice. Note: This produces a very accurate output, but that includes depending on the size of your terminal to be the same. You can clear screens or even resize the terminal for others using this function; I use it in conjunction with the "mid" command in my list.

Mouse Tracking
Will track your mouse and save it to a file. You can use gnuplot to graph it: $ gnuplot -persist

Synchronize date and time with a server over ssh
Set Remote Server Date using Local Server Time (push)

Perl One Liner to Generate a Random IP Address
A bash version.

A line across the entire width of the terminal
Use tput cols to find the width of the terminal and set it as the minimum field width.

Change/Modify timestamp

set a reminder for 5 days in the future
setup for reminder in 5 days, added the date in the future. To run a job at 4pm three days from now, you would do at 4pm + 3 days, to run a job at 10:00am on July 31, you would do at 10am Jul 31 and to run a job at 1am tomorrow, you would do at 1am tomorrow.
