 Useful Bash code, with no particular order
+===== Add safeguards on every script =====
+At the top of the file, always start your scripts with:
+<code bash>
+set -euo pipefail
+</code>
+  * ''-e'': The -e option will cause a bash script to exit immediately when a command fails.
+  * ''-o pipefail'': This particular option sets the exit code of a pipeline to that of the rightmost command to exit with a non-zero status, or to zero if all commands of the pipeline exit successfully.
+  * ''-u'': This option causes the bash shell to treat unset variables as an error and exit immediately.
