 Don't know if indentation means anything to the shell, but your top
file has a ";" where the second has a ":".

"""
When the shell sees a semicolon (;) on a command line, it's treated as a
command separator -- basically like pressing the ENTER key to execute a
command.

 Based upon
https://www.geeksforgeeks.org/conditional-statements-shell-script/ the
"then" is taken as a command (the examples all put it on the line UNDER the
"if") so the ";" is likely correct. No idea what the ":" version was doing
with it... Other than not seeing the "then" as a command.

 And here, both of the lines from the second file have ":" at the end.
You seem to have /something/ that seems to have created a lot of ":" where
they don't belong.
