in reply to Re^2: reading from file.
in thread reading from file.
Although there are several solutions for your task, consider the following:
use warnings; use strict; my $names = 'names.txt'; my ( $found, $name ); print 'Enter a name: '; chomp( my $input = <STDIN> ); open my $fh, '<', $names or die "Cannot open $names: $!\n"; while ( $name = <$fh> ) { chomp $name; if ( $input eq $name ) { $found++; last; } } close $fh; if ($found) { print qq{The name "$input" was found.\n}; } else { print qq{The name "$input" was not found.\n}; }
Note that:
- The name to search for is requested first.
- chomp is used to remove the trailing input record separator (usually \n), from both the entered name and the names from the file.
- The names' file is read once; no hash or array is necessary to 'hold' the names (Why process the list twice?). A flag's set and the while loop is immediately exited if the name is found.
- Appropriate responses are given depending upon the value of $found.
Hope this helps!
