How can I use avconv to convert multiple files in the terminal?

http://askubuntu.com – I'm new to Linux and I want to execute one command on every file in a loop: avconv -i *.mp4 -vcodec copy -ac 2 -strict experimental *.mp4 Can any one tell me how I can do this? I have more than 100 files to convert. I just want to convert them into new files with the same names, but using different codecs. It works for one file but I don't know how to run it on all of the files. I found this avconv documentation but I can't find the answer in there either. (HowTos)
