The first place to look is glob, since it appears that you don't want to recurse down a directory tree. As an example (NOT TESTED)
# insert appropriate shebang line
use strict;
use warnings;
my @files = glob("chat/*.htm"); # use something like [Hh][Tt][Mm] if y
+ou're unsure about the case
@files = grep { -s $_ and -f _ and -r _} @list;
print "Enter search string :";
my $string = <>; # read from STDIN
chomp($string); # strip off the line feed resulting from <enter>
my $quoted_string = quotemeta($string); # quote all meta-characters.
+ Remove if not needed
foreach my $file (@files) {
my $filehandle;
unless(open($filehandle, "<", $file)) {
warn "Could not open $file because $!\n";
next;
}
my @contents = <$filehandle>; # presuming the files are not too la
+rge
chomp(@contents);
close($filehandle) or die "Could't close $file because $!\n";
@contents = grep { /$quoted_string/ } @contents;
if(@contents){
print "$string was found in $file:\n\t",join("\n\t",@contents),
+"\n";
}
}
Warning! Code is NOT tested, and I won't even guarantee it will compile.
Doubtless there are better ways to do this than my example. One obvious improvement could be to slurp up the entire file into a scalar, not read it into an array, by setting $/ to undef; this is probably faster. Other improvements would be to permit regex.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
