I have two questions.
1) I'm trying to let the user type his "directory path" (perl example.pl /Users/name/file) in order to show the files or directory folder, i also wanted to show if the file or directory can or cannot be read, written, and executed
This the code i came up with.. but i still wanted to know if i can find the way of indicating if the file or directory and if it can or cannot be
read, written, and executed. I also wanted to make sure about what i making is good on other systems ( Linux/Unix/Mac)
Code:
#!/usr/bin/perl -w
use strict;
my $dir = shift || die "Argument missing: Please make sure from your directory name\n";
my $dir = "..";
opendir DIR, $dir;
my @values = readdir(DIR);
closedir DIR;
foreach (@values) {
printf "$_ is a file\n" if -f "$dir/$_";
printf "$_ is a dir\n" if -d "$dir/$_";
}
2) Question 2, i want to print out elements of hash and i want to use different ways of listing them.. just as each funiction, keys function,
values function and finaly sort keys.. and what i did was the following code and i don't know where is my problem...
$A = user input..
$B = user input..
Code:
#!/usr/bin/perl -w
use strict;
print "Enter A: ";
$A = <STDIN>;
chomp $A;
print "Enter B: ";
$B = <STDIN>;
chomp $B;
my %hash = (
'A' => "$A",
'B' => "$B",
'Z' => 'Z',
'D' => 'D',
'H' => 'H',
);
print "A: $hash{ 'A' }\n";
print "B: $hash{ 'B' }\n";
print "Z: $hash{ 'Z' }\n";
print "D: $hash{ 'D' }\n";
print "H: $hash{ 'H' }\n";
These are the 2 questions that i'm facing problem with...
