rbash:tldr:8dc42

The command you provided, rbash ${path-to-script.sh}, is invoking the rbash command with the argument ${path-to-script.sh}. Let's break it down:

1. rbash: rbash stands for restricted bash, which is a restricted version of the Bash shell. It provides limited access to the file system and certain commands, making it useful for creating restricted environments for user accounts or for executing potentially unsafe scripts.

2. ${path-to-script.sh}: ${path-to-script.sh} is a placeholder for the actual path to a specific Bash script (e.g., /home/user/myscript.sh). This variable is typically provided by the user to specify the path to the script they want to run.

By combining these two elements, the command rbash ${path-to-script.sh} instructs the system to launch the specified script using the restricted bash environment (rbash). The script will then run within the limitations and restrictions imposed by the restricted shell, ensuring limited access to system resources and commands.
