Permission denied error in github actions - github

Question

I have written a github action to retrieve the changed sql files and lint those changed files using sqlfluff.
Here is my github action code:
name: files_lint
on:
- pull_request
jobs:
lint:
runs-on: ubuntu-latest
steps:
- name: checkout
uses: actions/checkout#v2
- name: Install Python
uses: "actions/setup-python#v2"
with:
python-version: "3.7"
- name: install sqlfluff
run: "pip install sqlfluff"
- name: Get changed .sql files
id: linting
run: some code to get the changed files
- name: Linting files started
id: sql_linting
if: steps.linting.outputs.lintees != ''
shell: bash -l {0}
run: ${{ steps.linting.outputs.lintees }} > sqlfluff fix --force
But when I run ${{ steps.linting.outputs.lintees }} > sqlfluff fix --force on the changed sql files in the above github action, I'm getting an error
/home/runner/work/_temp/a41i1c89a4.sh: line 1: test.sql: Permission denied
Error: Process completed with exit code 126.

Answer 1

You can’t redirect files like this:
run: ${{ steps.linting.outputs.lintees }} > sqlfluff fix --force
This is attempting to write the output of whatever that command is - but I’d guess it’s a list of files rather than a command?
You should pass as parameters (assuming it’s a list of files):
run: sqlfluff fix --force ${{ steps.linting.outputs.lintees }}
Also I presume you’re going to do something with it afterwards? If not the fixed files will not do anything. If you just want to check the files sqlfluff lint would be better than sqlfluff fix (and catches more issues as sqlfluff fix only looks at rules it can fix).

For all developers who created shell script (.sh) locally on Windows or in Windows Subsystem Linux (WSL), or cloned the git repository without knowing on which file system this shell script was created, make sure that shell script is Linux executable!
Linux
chmod +x script.sh
Windows
git update-index --chmod=+x script.sh
Finally, don't forget to push your changes.
git add script.sh
git commit -m'Making script.sh executable'
git push
