Cool.
I love these little shell tricks... I'm personally particularly fond
of the old "(cd dir1; tar c) | (cd dir2; tar xv)" thing, but it's been
discussed here extensively before.
Also, seems that not many people are aware of "process substitution"
in bash: you do something like "diff <(ls dir1) <(ls dir2)", and bash
runs two ls's, each writing to a FIFO, and diff gets the names of
these two FIFOs as parameters. Output redirection also works. I'm not
sure how portable it is, though.
Does anyone else like these tricks? I'd love to hear about other
people's.
