It's relatively simple to use
find to look for recent files.
find . -cmin -5 will look for all files changed in the last 5 minutes under the current directory.
find is very much slower than
mdfind, which is powered by Spotlight's index when you search the whole machine.
What is the simplest way, on the terminal, to ask mdfind to only look for files modified in the last 5 minutes? Every time I look at the Apple doc I get totally lost as to what you actually type on the command line.
