New to perl

[Gus]

What would the syntax be for the follwing?

I want to cat /admin/log/fileA, and grep any lines that have the name
"joe", then send the output to /admin/log/fileB. Then I want to view
/admin/log/fileB

I want to cat /admin/log/fileA, and grep any lines that have today's
dat in them, then send that output to /admin/log/fileC. Then I want to
view that file.

New to perl ... thanks for the help.

Thanks!

Why use Perl for this when you have other tools to make it easy?

grep "joe" /admin/log/fileA | tee /admin/log/fileB | less

I don't know why you need to save the grepped stuff to fileB, but tee
will do it.

It's September. I smell homework.

I don't think so. Maybe you meant to say you want to read /admin/log/fileA?
If yes, then please see
perldoc -f open
including the examples.
If no, then you should ask in a group that deals with the tool "cat".

and grep any lines that have the name
"joe",

perldoc -f grep

then send the output to /admin/log/fileB.

perldoc -f open
perldoc -f print

Then I want to view
/admin/log/fileB

perldoc -f open
perldoc -f print

I want to cat /admin/log/fileA, and grep any lines that have today's
dat in them, then send that output to /admin/log/fileC. Then I want to
view that file.

Only new item in this list would be
perldoc -f time
perldoc -f localtime
