PyBash 0.1.1

>execute bash commands from python easily

PyBash

Streamline bash-command execution from python with an easy-to-use syntax. It combines the simplicity of writing bash scripts with the flexibility of python. Behind the scenes, any line starting with > is transformed to python subprocess calls and then injected into sys.meta_path as an import hook. All possible thanks to the wonderful ideas project!

Examples

Simple execution with output

>python --version
>echo \\nthis is an echo

outputs:

Python 3.9.15

this is an echo

Set output to variable and parse

out = >cat test.txt
test_data = out.decode('utf-8').strip()
print(test_data.replace("HELLO", "HOWDY"))

outputs:

HOWDY WORLD

Wrapped, in-line execution and parsing

print((>cat test.txt).decode('utf-8').strip())

outputs:

HELLO WORLD

Redirection

>echo "hello" >> test4.txt

Pipe chaining

>cat test.txt | sed 's/HELLO/HOWDY/g' | sed 's/HOW/WHY/g' | sed 's/WHY/WHEN/g'

outputs:

WHENDY WORLD

Redirection chaining

>cat test.txt | sed 's/HELLO/HOWDY\\n/g' > test1.txt >> test2.txt > test3.txt

Chaining pipes and redirection- works in tandem!

>cat test.txt | sed 's/HELLO/HOWDY\\n/g' > test5.txt

Also works inside methods!

# PYBASH DEMO #
def cp_test():
    >cp test.txt test_copy.txt

cp_test()

Usage

1. pip install pybash
2. python run.py OR directly, python -m ideas demo -a pybash

TODO

• Redirection: >echo "hello" >> test.txt
• Pipes: >cat test.txt | sed 's/HELLO/HOWDY/g'
