What output do you get from the commands:
Code:
pwd
printf '%s\n' "$PATH"
ls -l my-hilite
type env bash

when run in the directory where you installed my-hilite?
# 9  
Code:
andy@7_~/bin$ pwd
/home/andy/bin
andy@7_~/bin$ printf '%s\n' "$PATH"
/home/andy/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
andy@7_~/bin$ ls -l my-hilite
ls: cannot access 'my-hilite': No such file or directory
andy@7_~/bin$ type env bash
env is /usr/bin/env
bash is /bin/bash

I named my script Hilite.sh if that makes a difference.

It makes a difference.

If someone gives you a script named my_hilite and you do not install it with the name my-hilite, then you need to change everything that references my-hilite to reference whatever named you used when you installed it instead.

And, when you install it you have to make sure that the script will be readable and executable by whatever users want to run that script.

Code:
chmod 755 Hilite.sh

should give you a reasonably readable, executable script. Then you just have to find EVERYTHING that attempts to invoke my-hilite and change every reference to it to be Hilite.sh.

Sorry, and thank you wisecracker. I have now fixed this blunder in post #10.

I renamed it back to orig name.

Code:
my-hilite.sh

-----
 Results, file missing:
/home/andy/bin/my-hilite.sh: line 24: my-hilite: command not found

-----
 Results, file present:
/home/andy/bin/my-hilite.sh: line 32: my-hilite: command not found

-----
 Results, if only string "File" should be colored:
/home/andy/bin/my-hilite.sh: line 40: my-hilite: command not found

The scripts is relying on my-hilite which does not exist.

Code:
else
  echo "File $FILE does NOT exist." |
  my-hilite -f red
