mkpath equivalent for chown [Perl]

How can I execute chown for all the directories on a given path (similar to mkpath in perl).

i.e. if I give 开发者_运维问答/home/parth/something/else and as input, all of the directories on this path will have that owner. Is there an inbuilt function ?

There are no built-in functions for it. However, you can use the core module File::Find to traverse directory tree, getpwnam to get UID, and chown to change ownership.

#!/usr/bin/env perl

use strict;
use warnings;

use File::Find;

sub usage {
    die "Usage: $0 USERNAME PATH\n";
}

my $username = shift or die usage;
my $uid = ( getpwnam $username )[2] or die "Non-existent user.\n";

my $path = shift or die usage;
if ( !-e $path ) {
    die "Non-existent path.\n";
}

find( \&traverse, $path );

sub traverse {
    chown $uid, -1, $_ or die "Failed to chown [$_]: $!";
}

Usage

chown_path USERNAME PATH

Use File::Find::Rule to identify the files to change, then use chown on the files found.

use File::File::Rule qw( );

my $uid = getpwnam('...') or die;
my $gid = getgrnam('...') or die;

for my $qfn (File::Find::Rule->in('/home/parth/something/else')) {
   chown($uid, $gid, $qfn)
      or warn("chown $qfn: $!\n");
}
