Perl getpwnam Function
This function returns a list of fields In list context, as extracted from the /etc/passwd file, based on the user name specified by EXPR. It's generally used like this:
($name, $passwd, $uid, $gid, $quota, $comment, $gcos, $dir, $shell) = getpwnam ($user);
In a scalar context, returns the numeric user ID. If you are trying to access the whole /etc/passwd file, you should use the getpwent function. If you want to access the details by user ID, use getpwuid.
Following is the simple syntax for this function:
This function returns user ID in scalar context and user record (name, password, user ID, group ID, quote, comment, real name, home directory, shell) in list context.
Following is the example code showing its basic usage:
#!/usr/bin/perl ($name, $passwd, $uid, $gid, $quota, $comment, $gcos, $dir, $shell) = getpwnam("root"); print "Name = $name\n"; print "Password = $passwd\n"; print "UID = $uid\n"; print "GID = $gid\n"; print "Quota = $quota\n"; print "Comment = $comment\n"; print "Gcos = $gcos\n"; print "HOME DIR = $dir\n"; print "Shell = $shell\n";
When above code is executed, it produced following result
Name = root Password = x UID = 0 GID = 0 Quota = Comment = Gcos = root HOME DIR = /root Shell = /bin/bash
