Merging AVI together

I sometimes find in my video collection of multiple AVI files, in windows I had to use complex software to try and get the videos into a single file. However, in linux there's a terminal friendly method.

1. Download and install transcode package using sudo apt-get install transcode
2. The transcode package contains a utility called avimerge, use this to merge the two files together: avimerge -o outputfilename.avi -i firstFile.avi secondFile.avi thirdFile.avi 

Make sure you check the output file to make sure that it has joined everything properly, one way to do this is to check the ends of the files to see the transition - this should be seamless if the two files are meant to flow from one to the other.
