• sed or awk inserting of a command among a large string of variables

  9 octobre 2017, par tdiguy

  I have a program that I want to alter how it works a little, namely ffmpeg.
  I want to get ffmpeg to use libmp3lame as a audio encoder. The media server I use does not have this as an option. I am thinking that if I can use something like sed or awk in a script it would work. Basically i need to take 20+ variables and at a certain point ( say before /path ) I need to insert -c:a libmp3lame and then have it spit out the rest of the variables.
