Searchin for a word in a text file?

Try this. My regex might be off, but this will get you going.
#!usr/bin/perl
$count = 0;
$word = "WordToSearchFor";
open (FILE, /path/to/file.ext) or die "Can't open file: $!";
while ($line = <FILE>)
{
if ($line = ~s/$word//ig)
{
$count++;
}
}
print "The number of times the word $word appears is $count\n";
#!usr/bin/perl
$count = 0;
$word = "WordToSearchFor";
open (FILE, /path/to/file.ext) or die "Can't open file: $!";
while ($line = <FILE>)
{
if ($line = ~s/$word//ig)
{
$count++;
}
}
print "The number of times the word $word appears is $count\n";
A few minor tweaks....
- The 'if' on the regex would only do the first instance of a match in a line. If the word occurred in the line more than once, you'd miss all after the first one.
- Also, your regex is doing a replace which is not needed. You can just check for a match and increment $count on each match.
'hope this helps
