Easy aliaser for bash. If you keep navigating to directories to run files, easyalias them.

easyalias.py

#!/usr/bin/python

'''
Bash RC aliaser
Usage: easyalias aliasName aliasPath
Outputs: run source ~/.bashrc for commands to take effect

Configuration: If you have a different shell or your bashrc is somewhere other than ~/.bashrc, you'll need to change it.
It wouldn't be a bad idea to use ~/.bash_aliases instead of your bash file directly (changing config will do it).

Make sure you have the following in your bash config
if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases


To use: Add this file to somewhere on your bash path. Make executable (chmod +x easyalias.py).

Use similar to below - it will resolve ~/ and ./ in paths (~/ is automatically expanded in linux to the user directory), whereas ./ is handled by Python.

$ cd ~/Downloads/Sublime\ Text\ 2/
$ easyalias my_time_is_sublime ./sublime_text
$ source ~/.bashrc
$ my_time_is_sublime
 **sublime text opens**
