Tool like Media File Segmenter for Linux
I know that one can use ffmpeg to extract a smallfile.avi from a largfile.avi. But What I am looking for is an tool/command to split a large file into several files of a given size.
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Use split tool available for all UNIX-like systems. For example, to split a file in 100 MiB chunks.
Refer to the manual for more information (man split)
