Found how how much memory in kB $PID is occupying in Linux

The "proportional set size" is probably the closest representation of how much active memory a process is using in the Linux virtual memory stack. This number should also closely represent the %mem found in ps(1), htop(1), and other utilities.

Joins two pdf documents coming from a simplex document feed scanner. Needs pdftk >1.44 w/ shuffle.

Generate SHA1 hash for each file in a list

List files and pass to openssl to calculate the hash for each file.

Get the IP address of a machine. Just the IP, no junk.

Convert clipboard HTML content to markdown (for github, trello, etc)

I always wanted to be able to copy formatted HTML, like from emails, on trello cards or READMEs... but the formatting is always wrong... But from this two links: * https://jeremywsherman.com/blog/2012/02/08/pasting-html-into-markdown/ * http://stackoverflow.com/questions/3261379/getting-html-source-or-rich-text-from-the-x-clipboard For instance, to to copy an formatted email to a trello card, just: 1. Select the email body 2. run: xclip -selection clipboard -o -t text/html | pandoc -f html -t markdown_github - | xclip -i -t text/plain 3. Paste in your trello card 4. Profit! 8-)

32 bits or 64 bits?

Print random emoji in terminal

This will print a random emoji within the range of 1F600 - 1F64F, which includes all the face emoji. Obviously, this will only show something meaningful if your terminal can display emoji, but it may be useful in scripts. This likely requires recent versions of bash
