Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options

This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.

usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…

Getting help:
    -h — print basic options
    -h long — print more options
    -h full — print all options (including all format and codec specific options, very long)

Bash

for file in prefix*; do mv "$file" "${file#prefix}"; done;

The for loop iterates over all files with the prefix. The do removes from all those files iterated over the prefix.

Here is an example to remove "bla_" form the following files:

bla_1.txt
bla_2.txt
