Searching files opened by Perl Script ->HE~
Fra : Sonahl


Dato : 13-04-01 22:47

Hi, I need help using Perl. I've tried looking through websites, but to no
avail. See, my program is supposed to search a phonebook depending on certain
criteria. I was able to create the phonebook, I was able to add entries to the
phonebook, but now, I don't know how to search the phonebook using the Perl
script.

Usually, without a perl script, I'd use the command

grep Ray phonebook

which means to display lines that contain "Ray" in it, but now, I just don't
know how to go about doing this. If you can help, I'll greatly appreciate it.

You should go to your favorite bookstore and buy one or more of Ora's
<http://perl.ora.com/> great perl-books to get some fundamental
understanding of perl programming.

perl -e 'print grep /Ray/, (<>)' < phonebook

perldoc -f grep is your friend
