Ubuntu 22.04 - scenarios to Execute bash Script with 'Permission Denied' Even with 755 Permissions
I've searched everywhere and can't find a clear answer. I'm reviewing some code and I'm working with a frustrating scenario with executing a bash script on my Ubuntu 22.04 server... I have a script located at `/opt/scripts/myscript.sh`, and even though I set the permissions to 755, I still get a 'Permission Denied' behavior when I try to run it. Here's what I've done so far: I checked the permissions using `ls -l /opt/scripts/myscript.sh` and confirmed it shows `-rwxr-xr-x`. I also ensured that the script's shebang line is correct, as the first line of my script is `#!/bin/bash`. When I try to execute it with `./myscript.sh`, I get the following behavior: ``` -bash: ./myscript.sh: Permission denied ``` To troubleshoot, I also tried running the script with `bash myscript.sh` and it worked without any issues, but I want to run it directly. I checked the parent directory permissions as well and confirmed that `/opt/scripts/` has the correct permissions set to `755` as well. Additionally, I ran `getfacl /opt/scripts/myscript.sh` and found that there are no ACLs set which would restrict access. I even attempted to create a new script in my home directory with the same content and had no issues running that one. It seems to be isolated to this specific script in `/opt/scripts`. Can anyone suggest what else I could check to resolve this scenario? Is there a known question with executing scripts from certain directories in Ubuntu 22.04? Any ideas what could be causing this? This is my first time working with Bash stable. I'd love to hear your thoughts on this.
