Commands using python

Convert JSON to YAML.

Note that you'll need to have PyYaml installed.

Converts YAML file to JSON.

Note that you'll need to install PyYAML. Also some YAML data types (like dates) are not supported by JSON).

Generate a 18 character password from character set a-zA-Z0-9 from /dev/urandom, pipe the output to Python which prints the password on standard out and in crypt sha512 form.

you need ruby gems and localtunnel, further instruction on their website

for ubuntu precise, just intall ...

sudo apt-get install ruby ruby1.8-dev rubygems1.8 libopenssl-ruby

sudo gem install localtunnel

ssh-keygen -t rsa

python -m SimpleHTTPServer 8000

sudo localtunnel -k ~/.ssh/id_rsa.pub 8000

(1) required: python-googl ( install by: pip install python-googl )

(2) get from google API console https://code.google.com/apis/console/

Realtime lines per second in a log file using python ... identical to perl version, except python is much better :)

useful if you are using lots of data URI's in your css files

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

You can use "decode()" in a similar manner:

Python is always such much more readable than most shell scripting.

Remove dashes, also validates if it's a valid UUID (in contrast to simple string-replacement)

This opens a python command line. You can use math and random and float-division is enabled (without appending .0 to integers). I just don't know how to specify a standard precision.

ZenCart uses a MD5 with a salt to secure its passwords. If you need to forcibly change someone's password to a known value within the database, this one-liner can generate the password. Change the value of 'p' to the password you want.

A common programming question for interviewers to ask potential job candidates is to code "FizzBuzz". That is, if a number is divisible by 3, then it should display "Fizz". If a number is divisible by 5, it should display "Buzz". If it is divisible by both, then it should display "FizzBuzz". Otherwise, display the current number between 1 and 100.

This works on all versions of python 2.X.

Tested on Linux and bundled python versions on Mac OSX and Solaris / UNIX

Note: Serves globally on port 8000.

Ctrl+c to stop.

Don't start the server and leave it on a internet connected machine. :)

"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.

In Python version 3, the module was merged into http.server. Gentlemen, change your aliases.
