Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

Find & remove files that are duplicates but with different extensions recursively

Very useful to get rid of backup files or wrong extension files that lure in your folders In this example first I do two searches for all filenames of the two extensions .jpg and .png, then delete the extension and only output the now duplicate files. I loop with these results and print a log and delete the file with the extension I dislike. Show Sample Output

Remove color codes (special characters) with sed

This command builds upon some of the original commands posted here. Additions - The control sequence \x1b(B which selects the default character set ASCII. - Either the \x1B style escape sequence or the \033. - Case insensitivity by using 'I' to include \x1b, \x1B escapes and a-zA-Z in the latter part Tested extensively on makefile unbuffered output where the above additions proved necessary

Convert rich text on the clipboard to Markdown in OS X

This is useful for converting a piece of text from a browser or a PDF reader to Markdown. pbpaste -Prefer rtf no longer works for getting the rich text version of the clipboard. markdown_strict uses Markdown.pl syntax without Pandoc extensions. --no-wrap disables hard wrapping and --atx-headers uses ATX headers instead of SETEX headers. You can also use osascript -e'get the clipboard as"HTML"'|sed 's/«data HTML//;s/»//'|xxd -r -p to get an HTML version of the clipboard which is included for text copied from a web view in applications like Safari and Chrome.

Cleanup remote git repository of all branches already merged into master

Emergency Alien Invasion Warning

When aliens invade Earth, be first to warn your neighbours by placing your computer screen at a window and executing this potentially Earth-saving command. Ctrl C when aliens are defeated.

ssh and attach to a screen in one line.

If you know the benefits of screen, then this might come in handy for you. Instead of ssh'ing into a machine and then running a screen command, this can all be done on one line instead. Just have the person on the machine your ssh'ing into run something like $ screen -S debug Then you would run $ ssh -t user@host screen -x debug and be attached to the same screen session.

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
