Bash script scenarios to capture output of background process in Ubuntu 20.04
I'm having trouble with I'm working on a personal project and I'm trying to run a background process in a bash script and capture its output, but I'm working with issues with the output not being stored as expected... My script looks something like this: ```bash #!/bin/bash function run_background_task() { sleep 5 echo "Background task completed" } run_background_task > output.log 2>&1 & wait if [[ -f output.log ]]; then cat output.log rm output.log else echo "Output file not created" fi ``` When I execute the script, it runs without errors, but the `output.log` file is not created. I expected it to contain the message from the background task. I've tried running the script with `bash -x script.sh` to enable debugging, and it shows that the background task is being invoked, but the output redirection seems to be failing. I've also checked the permissions of the directory where the script is running, and I have write access. Running the background task directly in the terminal produces the expected output. Could there be a shell option or configuration that affects how output redirection works in a background process? Any help in understanding why this is happening would be greatly appreciated! My development environment is Ubuntu. What's the best practice here? Thanks for any help you can provide! I'm using Bash stable in this project. Thanks for your help in advance!
