Searching a text file
|
Can't Post
|
|
I am creating a script which is meant to search a text file for a specific text string which has been entered by a user.
#!/usr/bin/perl
print "What is your username?\n";
chomp($username = <STDIN>);
my $filename = "usernames.txt";
open FILE, "<$filename" || die "Cannot open file\n";
while($line =~ <FILE>) {
if ($line =~ m/$username/)
{
print "That username exists\n";
}
};
**************************
Contents of the text file:
Username: dannyb_16
Username: carl_45
*************************
The script compiles successfully however, if i enter the username dannyb_16 for instance, it will not print the desired output. All i can assume is that i have made an error which is preventing the file from being searched. Is anyone able to see a problem with this?
Regards
