Having trouble getting my bash script to be executable

My script, learn-fork.sh, is the following, plus a lot of comments (which will be un-commented once I get the test lines to work)

#!/bin/bash
echo "Running from ${0}"

In addition to that file, I have another file that shows in Finder as learn-fork (no extension) but that shows up in the terminal as learn-fork.sh-e

Here are the permissions on those files.

-rwxr-xr-x  1 TuzsNewMacBook  admin       250 Jan  1 18:25 learn-fork.sh
-rwxr-xr-x@ 1 TuzsNewMacBook  admin       307 Jan  1 13:38 learn-fork.sh-e

Running learn-fork.sh works. Running learn-fork gives -bash: learn-fork: command not found.

If you want to invoke it with the command learn-fork, name the file learn-fork.

Exactly that, no extension whatsoever. Not learn-fork.sh, or learn-fork.sh-e, or anything else -- just learn-fork.

Treating a file extension as something separate that's not really part of a name is a Windows-ism; UNIX-y folks (and UNIX-y operating systems) don't believe in it. Thus, if you want a command named foo, the executable or script associated must be named foo, not foo.anything.

And it must be marked as executable with chmod +x foo AND called with a correct path reference, either ./foo or /path/to/foo OR where /path/to is included in the PATH variable, i.e. export PATH="/path/to:$PATH".
