A Linux administrator received a permission denied error on a script. Which command would BEST resolve this issue?

• A. chmod +x startUp.sh
• B. sudo startUp.sh
• C. sh startUp.sh
• D. chmod 755 startUp.sh

Answer: (A)

Using the command to modify file permissions is the most effective way to address a permission denied error encountered while attempting to execute a script. The `chmod +x startUp.sh` command specifically changes the mode of the script file to make it executable. By adding the execute permission (represented by the `+x`), the administrator ensures that the script can be run by the user, which is necessary if the script is meant to be executed as a program. This approach directly resolves the permission issue by modifying the file's permissions to allow execution, which is the expected solution in this scenario. In most Unix and Linux systems, a script must have executable permissions set in order for users to run it. Thus, using this command effectively aligns with resolving the permission denied issue that the administrator is facing.
