Removing users from sudoers - help needed

I'm trying to create a script to remove users from sudoers on multiple servers. I'm able to do this with a one-line script using sed, but only if it's on one server.
Example: sed '/someuser/d' /host/local/etc/sudoers
Also, I think the problem with this one-line script is that I would have to redirect my output to another sudoers file (sudoers.new) and then mv that file to sudoers for it to work more effectively.

Since the hosts are tied to the ldap server I can just run the script from there by changing the host path without having to log into multiple servers.

I'm trying to write this in Perl, but for some reason I think it could be done easier in Bash.

Does anyone have any examples to help me get started?

This is what I have so far in Perl, but I'm not sure how to continue or how to add the sed line in here.

#!/usr/bin/perl -w

# this script removes a user from sudoers file

@mysites = ("Alpha", "Echo", "India", "Joliet", "Kilo", "November",
"Papa", "Uniform", "Sierra", "Wiskey");

open(FILE, "@mysite/local/etc/sudoers");
@site = <FILE>;
close(FILE);

BASENAME(3)								 1							       BASENAME(3)

basename - Returns trailing name component of path

SYNOPSIS
string basename (string $path, [string $suffix]) DESCRIPTION
Given a string containing the path to a file or directory, this function will return the trailing name component. PARAMETERS
o $path - A path. On Windows, both slash ( /) and backslash ( ) are used as directory separator character. In other environments, it is the forward slash ( /). o $suffix - If the name component ends in $suffix this will also be cut off. RETURN VALUES
Returns the base name of the given $path. EXAMPLES
Example #1 basename(3) example <?php echo "1) ".basename("/etc/sudoers.d", ".d").PHP_EOL; echo "2) ".basename("/etc/sudoers.d").PHP_EOL; echo "3) ".basename("/etc/passwd").PHP_EOL; echo "4) ".basename("/etc/").PHP_EOL; echo "5) ".basename(".").PHP_EOL; echo "6) ".basename("/"); ?> The above example will output: 1) sudoers 2) sudoers.d 3) passwd 4) etc 5) . 6) NOTES
Note basename(3) operates naively on the input string, and is not aware of the actual filesystem, or path components such as " ..". Note basename(3) is locale aware, so for it to see the correct basename with multibyte character paths, the matching locale must be set using the setlocale(3) function. SEE ALSO
