How can I randomly run for loop in sh of git action normally?

How can I randomly run for loop in sh of git action normally?

There is a github repository with daily commits here.

for github action

The yml file below exists.

name: planting-grass

on:
   schedule:
     - cron: '0 0 * * *'

jobs:
  task:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Set current date
        id: date
        run: echo "::set-output name=date::$(date +'%Y-%m-%d')"
      - name: Execute commands
        run: sh ./task.sh ${{ steps.date.outputs.date }}
      - name: Commit files
        run: |
          git config --global user.name "$(git --no-pager log --format=format:'%an' -n 1)"
          git config --global user.email "$(git --no-pager log --format=format:'%ae' -n 1)"
          git add date.txt
          git commit -m ${{ steps.date.outputs.date }}
      - name: Push changes
        uses: ad-m/github-push-action@master
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          branch: ${{ github.ref }}

This yml runs task.sh. task.sh looks like this:

#!/bin/bash

echo "DATE: $1" >> date.txt

everything works fine.

However, in data.txt, one line per day is accumulated.

I want to accumulate lines between 1 and 100 in data.txt.

Where can I edit to use the above function?

Then I tried the following:

#!/bin/bash

range=100
number=$((RANDOM % range))

while [ "$i" -le "$number" ]; do
    echo "DATE: $1" >> date.txt
done

#!/bin/bash

range=100
number=$((RANDOM % range))
i=0

while (( i <= number )); do
    echo "DATE: ${i}" >> date.txt
    i=$((i+1))
done

#!/bin/bash

range=100
number=$((RANDOM % range))

for i in $(seq 0 $number); do
    echo "DATE: ${i}" >> date.txt
done

But all failed.

It outputs the following error message:

./task.sh: 7: [: Illegal number:
./task.sh: 7: [[: not found
./task.sh: 7: i: not found

I wonder how can I run a normal random for loop.

Best Regards!

EDIT)

#!/bin/bash

range=100
number=$((RANDOM % range))
i=0

while (( i <= number )); do
     echo "DATE: ${i}" >> date.txt
     i=$((i+1))
done

The above code works fine, but it only works once. Unlike wanting to run echo "DATE: ${i}" >> date.txt randomly between 1 and 100, it is always executed only once. How can we resolve this problem?

  • You can change run: sh ./task.sh to run: bash ./task.sh to run your script with bash, instead of sh.

  • If your script is executable (chmod a+x task.sh, and commit the file), and you have the right shebang (#!/bin/bash), you can also do run: ./task.sh.

  • Your cron schedule (0 0 * * *) is set to run daily. If you want to run more frequently, you could change it. For example 0,30 * * * * will run every half an hour (the date will be the same all day unless you include the time, eg date + '%Y-%m%d_%H:%M:%S').
