Optimal way of deleting huge numbers of files
Using -delete is faster than:
find /path/to/dir -type f -print0 | xargs -0 rm
find /path/to/dir -type f -exec rm {} +
find /path/to/dir -type f -exec rm \-f {} \;
This command find all files in the current dir and subdirs, and replace all occurances of "oldstring" in every file with "newstring".
This command copies all filenames in the current dir and subdirs that end in .mp3 regardless of case (also matches .MP3 .mP3 and .Mp3) It copies all the files to the "mp3" folder in your home directory. If you want to see the files that are beeing copied, replace "cp {}" with "cp -v {}"
