But more likely to break. Melchior's original "while read i" bit is
not just extra words but a very useful idiom, especially in the
presence of the possibility of spaces in filenames (I don't know if
that's a concern in FG or not). Yes you could use -print0 and xargs -0
but "while read" is useful in many situations not all of which involve
find.
I might mention that no matter how quick and clever your shell
scripting, from where I sit it's 5 minutes for every flightgear
startup. Clearly, if one is short on time, this is the bottleneck.
