attempiting simple bash script, help please

Greetings
Cheery Christmas, and all that

I'm an avide user of mandrake linux, currently at 10.1, and also am an avid downloader of all that the world of newsgroups have to offer.

Recently Ive been attempting to use a bash script in linux to replace a .bat file for windows, that glues a group of split files back together.

The files are split originally using one of many available programs. These programs seems to produce similar split file groups, labeled file.mpg.001, file.mpg.002, etc..

The windoz script (.bat) looks like this :

@echo off
echo.
echo.
echo Recreating the Original File From the Pieces.
copy/b "REM-Live.mpeg.001" "REM-Live.mpeg"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.002"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.003"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.004"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.005"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.006"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.007"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.008"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.009"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.010"
copy/b "REM-Live.mpg" + "REM-Live.mpeg.011"
echo.
echo All Done Joining the Files.

Ive scoured the internet, google, and this site to find a reasonable way to convert this script, or to write a custom script using bash commands, possible cp, cat, or join.
Ive had no success, and would like any help that you could offer!
I'm not an expert in bash scripting, and really need some assistance.
Cheers!

Check whether a
ls -l blah.mpeg.*
gives you the files in the right order.
If it does:

cat blah.mpeg.* > blah.mpg

Cheers,
Tink

I'm not too familiar with .bat files, but what I think you want to do is this:

Code:

cat REM-Live.mpeg.001 > REM-Live.mpeg
cat REM-Live.mpeg.002 >> REM-Live.mpg
cat REM-Live.mpeg.003 >> REM-Live.mpg

and so on.

Thanks to you both!
It turn out that either approach gets some result.
Thsnks,
I was curious to see what the equivalent linux script would be, and as it turns out, one can replace an entire .bat file of text with a single line.
This rocks!
Cheers,
Have a good week.

Pleasure mate,

and unix/linux OWNS you... ;}

With a little knowledge and some thought with
those systems you can achieve things that would
require some heavy programming in a winDOHs-
environment ...

Tink
