Tunneling an SSH session through TOR for anonymity. Using openbsd's netcat. Tested on Ubuntu 14.04 This also works with any proxy type: http, socks4 and socks5 For http proxy, replace -X 5 with -X connect For socks4 proxy, replace -X 5 with -X 4 (DNS leak may occur) Proxy host defined after -x Replace -x localhost:9050 with proxy server of your choice

Useful, when you need to backup/copy/sync a folder over ssh with a non standard port number

Given a list of filenames, one per line, in /tmp/filelist, calculate the total sum disk usage.

Opens the appropriate graphical file browser for the current terminal eg nautlius.

I use screenflow to create and edit videos. The default storage for a single video is a folder. If I want to move that someplace, it's easier to zip up the folder and send it. If I'm making a series of short videos, I might have 10 folders. This will go through and make a single bz3 file for EACH folder.

Coming back to a project directory after sometime elsewhere? Need to know what the most recently modified files are? This little function "t" is one of my most frequent commands. I have a tcsh alias for it also: alias t 'ls -ltch \!* | head -20' Show Sample Output

This is a minimalistic version of the ubiquitious Google definition screen scraper. This version was designed not only to run fast, but to work using BusyBox. BusyBox is a collection of basic Unix tools that have been compiled into a single binary to save space on tiny installations of Unix. For example, although my phone doesn't have perl or the GNU utilities, it does have BusyBox's stripped down versions of wget, tr, and sed. It turns out that those tools suffice for many tasks. Known Bugs: This script does not handle HTML entities at all. I don't think there's an easy way to do that within BusyBox, but I'd love to see it if someone could do it. Also, this script can only define a single word, not phrases. (Well, you could if you typed in %20, but that'd be gross.) Lastly, this script does not show the URL where definitions were found. Given the randomness of the Net, that last bit of information is often key. Show Sample Output

indenting all the files at a time, if the file has local variable for indentation style its even better. This one liner is not pretty but it does the job.

Calculate pi from the infinite series 4/1 - 4/3 + 4/5 - 4/7 + ... This expansion was formulated by Gottfried Leibniz: http://en.wikipedia.org/wiki/Leibniz_formula_for_pi I helped rubenmoran create the sum of a sequence of numbers and he replied with a command for the sequence: 1 + 2 -3 + 4 ... This set me thinking. Transcendental numbers! seq provides the odd numbers 1, 3, 5 sed turns them into 4/1 4/3 4/5 paste inserts - and + bc -l does the calculation Note: 100 million iterations takes quite a while. 1 billion and I run out of memory.

Get http://xkcd.com/now image, inverts colors (I prefer dark backgrounds) and set it as wallpaper. You can replace the "convert" part by "wget -q http://imgs.xkcd.com/comics/now.png -O /tmp/now.png" if you prefer light backgrounds. The DISPLAY variable is here to work as a cron job.

This is like using cat to see the contents of several small files at once, but using 'more' to add a header to each one.
