# Bash really should be avoided as much as possible (within reasonable limits, of course) even for one-liners which *seem* trivial.
# Bash is very error-prone by design. It's hard to comprehend all the pitfalls (e.g. https://mywiki.wooledge.org/BashFAQ/105)
# and it's a regrettable time-waste anyway.
#
# Modern Python is good for scripting the logic - keep Bash only for launching executables and most primitive
# pipes and redirections (avoid subshells, substitutions and so on). No need to install anything -
# just start your script with the following small self-contained helper function (check the examples for usage). Its features:
# * terminates on non-zero exit status by default
# * returns the output (combined - which usually should not be a problem - use e.g. '2>/dev/null' when it is)
# * prints commands and combined output
