e: if a command fails, set -e will make the whole script exit, instead of just resuming on the next line.
o: set -o pipefail causes a pipeline to produce a failure return code if any command errors. Normally, pipelines only return a failure if the last command errors.
u: treat unset variables as an error, and immediately exit.
x: enable a mode of the shell where all executed commands are printed to the terminal.
