Pure Sh Bible - Hackdot

Have you not used Python or Perl much? Because both are full of footguns. And I don't see any advantage to for loops in a HLL. These are identical:

  for i in `seq 1 10` ; do
    echo i $i
  done

  for i in range(1,10):
    print("i %i\n")

You might find problems with the shell code, and I'll find problems with the Python. But both will print 1 to 10.

Personally I've found Python to have significantly fewer foot-guns than bash.

The biggest reason why I don't use it all of the time is that calling / piping commands takes a lot more typing, so it's easier to use bash for very simple shell scripts. And while there are libraries that simplify shell scripting, that adds external dependencies to your scripts.

This outputs "i %i\n\n" 9 times.

Come on, they aren't full of footguns in basic things like string comparison or variable assignment.

Most of the things on this list couldn't happen in Python:
