Only one think I didn't get (acctualy unrelated to question, but) : what is the fl[0-9]?
Whas it assumed the same as next: fl{0..9} ?
So, it would generate list of files: fl1 fl2 .. fl19
They are a couple examples of ways you could call multiple files (even more than just two) at the command line, courtesy of the shell, without writing one by one.
fl[0-9] would expand to
fl0 fl1 fl2 ... fl9 if they exist.
fl1{0..9} would expand to
fl10 fl11 fl12 fl13 ... fl19, and expects them to exist.

1. OS X (Apple)
I need a simple command line executable that allows me to join many wmv files into one output wmv file, preferrably in a simple way like this:
wmvjoin file1.wmv file2.wmv .... > outputfile.wmv
So what I want is the wmv-equivalent of mpgtx
I cannot find it on internet.
Thanks. (2 Replies)
