No it doesn't, for several reasons. First of all, you forgot to escape
the |. The shell was interpreting that whenever you executed the alias.
I assume you wanted the | passed to find, because you put a \; after it.
Second of all, even if you did escape the |, this wouldn't work because
find does not accept shell metacharacters. It would just stupidly pass
the | and more to grep as filenames.
Also, I'm not sure this does what you want. It runs more once for each
file it finds a string in (rather inefficient) and it prints the names
of all files that match the pattern, not just the ones that have the
string in them.
Try:
alias sea 'find \!:1 -name "\!:2" -exec grep \!:3 {} \; -print | more'
Although that prints the lines matched and THEN the file, if that's
acceptable. Or you could try:
alias sea 'find \!:1 -name "\!:2" -print | xargs grep \!:3 | more'
I suggest removing the double quotes around \!:2; they're rather
confusing. Something like "sea . *.c main" implies that you want the
shell to expand the *, which is not what happens.
You probably can't get EXACTLY what you want without writing either a
shell script or a ridiculously large alias.
#! /bin/sh
for i in `find "$1" -name "$2" -print | xargs grep -l "$3"`
do
echo $i
grep "$3" $i
done | more

And Dinsdale said, "You've been a naughty boy, Clement," and splits me nostrils
open, and saws me leg off, and pulls me liver out. And I said, "My name's not
Clement." And then he loses his temper. And he nails me head to the floor.
