pysh
Python-enhanced bash scripts.
pysh allows you to write bash scripts that include short snippets of Python
code with a local environment that is shared between bash and Python.
Example
Lines that start with #> are evaluated as Python:
##### From bash to python #####
bashVariable="Hello world"
#> print("{} from python!".format(bashVariable))
##### From python to bash #####
#> pythonVariable = " ".join(["Hello", "world"])
echo "$pythonVariable from bash!"
######## Back and forth #######
for file in *.csv; do
echo
echo "before: $file"
#> base, ext = os.path.splitext(file)
#> file = base.upper() + ext
echo "after: $file"
doneRun it:
> ls
dummy.csv important.csv example.sh
> pysh example.sh
Hello world from python!
Hello world from bash!
before: dummy.csv
after: DUMMY.csv
before: important.csv
after: IMPORTANT.csv
Caveats
This is only supported for Python 3.4 and above due to redirect_stdout.
Disclaimer / warning
This is a prototype implementation with lots of evil hacks.
