+# "-e": Exits immediately if a command exits with a non-zero status
+# "-u": Treats unset variables as an error, preventing unexpected behavior from undefined variables.
+# "-o pipefail": Causes a pipeline to return the exit status of the last command in the pipe that failed, ensuring errors in any part of a pipeline are not ignored.
