What is set -e?

set -e is a shell command that instructs the shell to exit immediately if a command exits with a non-zero status. This is a way to ensure that your script stops executing as soon as an error occurs, preventing subsequent commands from running based on potentially incorrect or incomplete results. It's a common practice to include set -e at the beginning of a script to enforce stricter error checking.
