I am new to perl and would like to parse text file content into hash and get the values for each line from the text file. For example, in example file below, I wanted to get the path for each line using $info{}{}{} method. My main code is what I tried but not working properly. </op>
#!/usr/bin/perl use strict; use warnings; my $file = "/path/to/config/config.txt"; my %info = parse($file); my %fruits; foreach $fruit (@fruits) { #get $address for each line in input file $path=$info{$name}{$fruit}{path}; #get $name for each line in input file $name=$info{name}{$fruit}{$path}; } sub parse { my $file = shift; my %info; return if !(-e $file); open(my $fh, "<", $file) or die "Can't open < $file: $!"; my $msg = "-I-: Reading from config file: $file\n"; print $msg; #print LOG $msg; my %seen; while (<$fh>) { if (($_=~/^#/)||($_=~/^\s+$/)) {next;} my @fields = split(" ", $_); my ($name, $fruit, $p) = @fields; if (!$seen{$fruit}) { push (@fruits,$fruit); $seen{$fruit}=1; } $info{$name}{$fruit}{path} = $p; } close $fh; return %info; }
Input file (with format of 3 categories: name fruit path, name and fruit could be same or different) Example:
Albert apple /path/to/somewhere/a Jack pineapple /path/to/somewhere/b Jack apple /path/to/somewhere/c Dex jackfruit /path/to/somewhere/d
