perl function chown

The chown function in Perl is used to change the owner and group of a file or directory. Here's an example of how to use chown:

# Set the owner of the file to "alice" and the group to "users"
my $file = "example.txt";
my $uid = getpwnam("alice");
my $gid = getgrnam("users");
chown $uid, $gid, $file;

In this example, the chown function is used to set the owner of the file "example.txt" to the user ID of the user "alice" and the group to the group ID of the group "users".

The getpwnam and getgrnam functions are used to look up the user ID and group ID based on their names. The chown function takes three arguments: the user ID, the group ID, and the path to the file or directory to modify.

It's important to note that in order to use chown, your script must be running with sufficient permissions to modify the ownership of the file or directory.
