and

FILES=$(find . -iname \"*.py\")
pylint -E $FILES

If

Answer 1

My one cent

find . -type f -name "*.py" | xargs pylint 

How does it work?

find finds all files ends with py and pass to xargs, xargs runs pylint command on each file.

NOTE: You can give any argument to pylint command as well.

EDIT:

According to doc we can use

1. pylint mymodule.py

2. pylint directory/mymodule.py

number 2 will work if directory is a python package (i.e. has an __init__.py file or it is an implicit namespace package) or if “directory” is in the python path.

Answer 2

Im using the "pylint_runner" in order to run pylint on all files in the directory and the subdirectories. Python 3.7.4

pylint_runner 0.54

pylint 2.4.1

https://pypi.org/project/pylint_runner/

Here is the command to run it from the Docker container:

docker run -i --rm --name my_container \
  -v "$PWD":"$PWD" -w "$PWD" \
    python:3.7 \
      /bin/sh -c "pip3 install -r requirements.txt; pylint_runner -v"

requirements.txt - should exist in the "$PWD" directory and contain "pylint_runner" entry.

Answer 3

Just pass the directory name to the pylint command. To lint all files in ./server:

pylint server

Answer 4

If your goal is to run pylint on all files in the current working directory and subfolders, here is one workaround. This script runs pylint on the current directory. If __init__.py does not exist, it creates it, runs pylint, then removes it.

#! /bin/bash -
if [[ ! -e __init__.py ]]; then
    touch __init__.py
    pylint `pwd`
    rm __init__.py
else
    pylint `pwd`
fi

Answer 5

1. touch __init__.py in the current directory
2. touch __init__.py in every subdirectory that you want pylint to look at
3. pylint $(pwd) (or equivalently pylint /absolute/path/to/current/directory)

Answer 6

To run pylint on all *.py files in a directory and its subdirectories, you can run:

shopt -s globstar  # for Bash
pylint ./**/*.py
