In particular I’ll show you: pgrep, grepcidr, ngrep, pdfgrep and taggrepper.

At the moment my favourite way to do (simple) elaborations and conversions of multimedia file is FFMPEG. But i understand that is not exactly the most user-friendly tool around, so if you don’t want to open the terminal and read the man page of FFMPEG perhaps you could take a look at Yakito.

But let’s see what you can do with it.
Sometimes is useful to run over and over again the same command until something happen, for example you could do a ls -lrt until a file has reached a certain dimension or is created, how to do it ?
Sure you can use bash history and use up arrow and return over and over again, or perhaps write some line of bash to get an infinite loop that run the same command, but there is a smarter approach to this : watch .
