github actions- if condition inside the for loop - github-actions

Question

I'm tring to run the below workflow using for loop with if condition inside, but the action is parsed with an error, what is my mistake?
workflow:
on:
push:
branches: [ "main" ]
pull_request:
branches: [ "main" ]
jobs:
analysis:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v3
- name: Setup Cpp Check
run: sudo apt-get install cppcheck
- name: Run Static Analysis
run: cppcheck . --force --error-exitcode=1
unit_test:
# needs: Scan_changes
runs-on: ubuntu-latest
steps:
- uses: actions/checkout#v3
- name: Setup Ruby
run: sudo apt-get install ruby
- name: Setup Ceedling
run: sudo gem install ceedling
- name: Get changed files
id: changed-files
uses: tj-actions/changed-files#v34
with:
dir_names: true
files: |
code/**
- name: Unit Test for Changed modules
run: |
for file in ${{ steps.changed-files.outputs.all_changed_files }}; do
if: contains('$file', 'SomeString')
echo "$file was changed"
done
- name: Test
run: |
ceedling
and the output is
So i'm not sure what is the propore syntex for the if condition inside the fore loop

Answer 1

is not valid bash script code. You should do something like:
- name: Unit Test for Changed modules
run: |
for file in ${{ steps.changed-files.outputs.all_changed_files }}; do
if [[ $file =~ "SomeString" ]]; then
echo "$file was changed"
fi
done
