PYTHON

kali linux run python script anywhere

# Make a python script:

cd /home/el/bin
touch stuff.py
chmod +x stuff.py

# Find out where your python is:

which python
/usr/bin/python

# Put this code in there:

#!/usr/bin/python
print "hi"

# Run in it the same directory:

python stuff.py

# Go up a directory and it's not available:

cd ..
stuff.py
-bash: stuff.py: command not found

# Not found! It's as we expect, add the file path of the python file to 
# the $PATH

vi ~/.bashrc

# Add the file:

export PATH=$PATH:/home/el/bin

# Save it out, re apply the .bashrc, and retry

source ~/.bashrc

# Try again:

cd /home/el
stuff.py

# Prints:

hi

# The trick is that the bash shell knows the language of the file via 
# the shebang.
