Batch help to modify a text file and make copy b4 modifying

[val5662]

Hi Guys...
I need the following batch file code modified so the original file is copied and renamed to "copy-original.txt" before modifying the original.
The batch file sorts out text file contents alphabetically , a at top , z at bottom.
The way it is now it leaves the original untouched and unnamed and makes a sorted alphabetically copy of original and is renamed.

@echo off
sort original.txt /o modified-original.txt
echo: FILE HAS BEEN SORTED ALPHABETICALLY TO AN OUTPUT FILE
echo: THE ORIGINAL HAS BEEN LEFT ALONE
pause

Thanks!
I appreciate your help.

Squashman....
I am guessing you meant to do it this way:

@echo off
ren original.txt copy-original.txt
sort copy-original.txt /o original.txt
pause

Anyway,it worked great.....Thanks a bunch!

rename original.txt copy-original.txt
