Poor man's unsort (randomize lines)

Puts the lines in a hash then iterates over the hash. Hashes are unsorted by nature. There should be newlines after each colon and an indent of two spaces, but it's still a one-liner.. kinda. The first line is the only one with no indent.

Serve the current directory at http://localhost:8000/

"this command line isn't mine but i find it very useful" ^^ This one-liner starts a dedicated server hosting (web server) on port 8000 with the contents of current directory on all the interfaces (address 0.0.0.0), not just localhost. If you have "index.html" or "index.htm" files, it will serve those, otherwise it will list the contents of the currently working directory. It works because python comes with a standard module called SimpleHTTPServer. The -m argument makes python to search for a module named SimpleHTTPServer.py in all the possible system locations (listed in sys.path and $PYTHONPATH shell variable). Once found, it executes it as a script. If you look at the source code of this module, you'll find that this module tests if it's run as a script if __name__ == '__main__', and if it is, it runs the test() method that makes it run a web server in the current directory.

Quickly re-launch your script (python for example)

Very useful for test a script. After launch this command, you only have to press ENTER for launch your script again. I work with screen and tape ENTER instead of '!!'+ENTER If you break your script with CTRL-C, it will wait for press ENTER and will re-launch You can write like it : while read -p "Press ENTER" ; do python ; done
This is sample output - yours may be different.

while read ; do python <script> ; done

recursive search and replace old with new string, inside files

recursively traverse the directory structure from . down, look for string "oldstring" in all files, and replace it with "newstring", wherever found also: $ grep -rl oldstring . |xargs perl -pi~ -e 's/oldstring/newstring'

list files recursively by size

Backup your OpenWRT config (only the config, not the whole system)

You only have to fill in your administrative account and password, and the router FQDN! I recommand to execute this command not over the internet, because there is no encryption (the username and password will be transmitted in plaintext!)

echo something backwards

NAME rev - reverse lines of a file or files SYNOPSIS rev [file ...] DESCRIPTION The rev utility copies the specified files to the standard output, reversing the order of characters in every line. If no files are specified, the standard input is read. AVAILABILITY The rev command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.

Blue Matrix

Same as original, but works in bash

Random quote from Borat -- no html parsing

Turns out smacie.com has a text file containing every single one of the borat quotes, each one on a newline. This makes it very convenient, as this can be done without any sed-parsing, and uses less bandwitdth! Note that borate quotes are quite offensive, much more so than "fortunes-off"!

Change host name

With sed you can replace strings on the fly.

Check which files are opened by Firefox then sort by largest size.

Check which files are opened by Firefox then sort by largest size (in MB). You can see all files opened by just replacing grep to "/". Useful if you'd like to debug and check which extensions or files are taking too much memory resources in Firefox.

Install pip with Proxy

Convert seconds to [DD:][HH:]MM:SS

Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }
