This works but I am trying to simulate with sed (GNU sed version 3.02)
(Gawk GNU Awk 3.1.0)
gawk -F" - " "$0=$2FS$1" input file > output file

I am also trying to use SpellCheck but need to know how to implement this sed syntax and see the results.

SpellCheck

Load Random Example
#!/bin/bash
file1$ "left - right"
sed "s/$.*$ - $.2$/\2 - \1/" file1$ > file2$
echo file2$

Syntax ok but how can I display the results here?
Please keep in mind I'm pretty green at RegEx
I am referencing all the suggested material given for help.

GNU Awk 3.1 is from 2002 and sed 3.0.2 was released in 1998!!

I refer again to my previous recommendation: ditch MKS Toolkit and just use MinGW (either via MSys2 or Git).

Then you will get current versions - and almost certainly the bug in Sed causing your problem will be solved.

I will update my setup with GIT

Sorry. Older ver was my sed problem.
sed 4.0.7 worked fine.
My cygwin\bin ver won't work in my TCC shell but my UnixUtl\bin ver 4.0.7 works.

I know you mentioned that before.

I will see if GIT works in my TCC shell next.

--Thanks

Yep, I was fairly sure it would - I've used Sed enough on Windows and never had problems with the line ending problem, but it's not surprising that such an old version does.

Also, for clarity, what you're referring to as "GIT" is "Git for Windows", which is a bundle that includes multiple things: Git version control, GNU Bash shell, and mingw-w64 (which provides GNU coreutils and others) - referring to it as either "Git Bash" or "MinGW" should be less confusing.

Yes, I got the Git for windows and extracted the portable version. Has all & more than I most likely will ever need.
This gets me over my major hurdles and ready for my next minor steps.
