Difference from (1) "cat /proc/pci| grep rev" and (2) "grep rev /proc/pci",
despite of the same material result, is important in my filosophy.
Solution (2) requires more disk space in the user's brain, because here "grep"
is used with two parameters. The user must recall the right syntax:
"grep rev /proc/pci" OR "grep /proc/pci rev" ?
And if you finally pretend to do a second filtering on the
keyword "ethernet"?
In this case, my usage is more symmetric of yours because I will write:
cat /proc/pci | grep rev | grep -i ethernet
while you, probabily, will write:
grep rev /proc/pci | grep -i ethernet
or, even worse, you will introduce the AND option in the grep (there is one?)
