I've been recording demos of true combat elite (a wolfenstein mod) game and found out that the only way to record this is in .tga sequence in the games folder in my home directory. That means that i have to move those images to my other partition because I'm running out of space on my main partition. Then i have to convert those to jpg using imagemagick and after that encode them to mjpeg avi using mencoder. That all works fine and I'm getting along well (as a newbie) with editing simple scripts (using "for" loops) to accomplish these tasks.
My question is this: Is it possible to use bash scripts to automate all of this in a one single command? If it is possible then can anyone point me to a good tutorial/book that I can learn how to do this. I have little to no experience in programming. Thank you.

Although I don't really know what you are doing...you can certainly stitch together individual linux commands into a bash script and do everything in one go. You can even put stops in script so it can abort if it encounters something abnormal.

I suggest you look at the Bash Beginner's guide and Advanced Bash Scripting guide on http://www.tldp.org/guides.html

Hope this helps.

Thanks a lot. I downloaded the guide and i think its what i was looking for.
