Install QEMU, avidemux, ffmpeg2theora, audacity on the host


$ sudo apt-get install qemu avidemux ffmpeg2theora audacity
 
Alternatively (preferably) qemu could be compiled from source. It's not nearly as hard as it sounds. There's a great guide to compiling QEMU on the Hampshire LUG wiki. Doing this means you can enable the (closed source) KQEMU module which dramatically improves performance of QEMU.

Replace a String in Multiple Files in Linux Using Grep and Sed

Command grep -rl matchstring somedir/ | xargs sed -i 's/string1/string2/g' Note: The forward slash '/' delimiter in the sed argument could also be a different delimiter (such as the pipe '|' character). The pipe delimiter might be useful when searching through a lot of html files if you didn't want to escape the forward slash, for instance. matchstring is the string you want to match, e.g., "football" string1 would ideally be the same string as matchstring, as the matchstring in the grep command will pipe only files with matchstring in them to sed. string2 is the string that replace string1. Example grep -rl '5.00.00.40' ./ | xargs sed -i 's/5.00.00.40\/vc/5.79.17.43\/BB/g' Extracted from : http://vasir.net/blog/ubuntu/replace_string_in_multiple_files/
