This week's Useless Use of Cat Award goes to...
"Hemant" == Hemant Shah <sh...@flood.xnet.com> who writes:
Hemant> cat file | sed -e "s!/u/!/!"
which, using the simple rule that:
cat fred | barney junk junk junk ...
can nearly always be rewritten as:
<fred barney junk junk junk ...
would look like this:
<file sed -e "s!/u/!/!"
But of course, we can go one further, because we know the operation of
"sed", and can put the file as one of the arguments:
sed -e "s!/u/!/!" file
and there you have it.
Stay tuned for next week's "Useless Use of Cat Award" (I'd bet the rent
money that there'll be another one).
Just another Useless Use of Usenet Award Winner,

The cat is useless:
sed -e "s!/u/!/!" file
