Cutting and Merging 2 Clips in Bash

Lets say you have a prank compilation and you only want to keep 2 specific cuts.

1 Cutting Clip
ffmpeg -ss <start time> -i original.mp4 -to <duration in seconds> cut.mp4
example: ffmpeg -ss 00:03:02 -i original.mp4 -to 0:33 cut.mp4

2 Merge
mencoder file1.mp4 file2.mp4 -ovc copy -oac pcm  -o merged.mp4

Both cuts need to be taken from the same original video
