Here’s a simple Perl script to read a file, count word occurrences, and display the results:
#!/usr/bin/perl
use strict;
use warnings;
# Check if a filename is provided
if (@ARGV != 1) {
die “Usage: perl script.pl filenamen”;
}
my $filename = $ARGV[0];
open(my $fh, ‘<‘, $filename) or die “Cannot open file: $!”;
my %word_count;
while (my $line = <$fh>) {
chomp $line;
my @words = split(/s+/, $line);
$word_count{$_}++ for @words;
}
close($fh);
# Display word frequencies
foreach my $word (sort keys %word_count) {
print “$word: $word_count{$word}n”;
}
“This tool needs a file name entry to read content from it and displays how often words appear in the text results. When you want customized Perl work our Programming Assignment Help team provides complete support for your projects.”
