help with for loop

I'm trying to run a script on multiple servers, I'm fairly new to all this so any help would be appreciated.

I have a list of servers in a file named pwords, I'm trying to run the script on each server in the list, how would I write the for loop for do execute this in bash?

script name is passwd_mgr.pl

thanks

I'm assuming you are looking for a perl script, considering the .pl extension. Here is what I came up with, using inner.pl script file as an example of the perl script being called:

script file --> inner.pl
Code:
#!/bin/perl

print "pinging $ARGV[$0] \n";
system ("ping $ARGV[$0]");

script file --> passwd_mgr.pl
Code:
#!/bin/perl

open FILE, "pwords" or die $!;
binmode FILE;

while (<FILE>) {
        print pinging $_;
        system ("perl inner.pl $_");
}
close (FILE);

I'm very new, and put this together and it runs. Here are the links I used:

http://www.perlfect.com/articles/perlfile.shtml
http://theos.in/perl/how-can-i-call-...-from-another/
http://www.devdaily.com/perl/edu/qanda/plqa00001.shtml

Is this close to what you were looking for ?

thanks for the replies guys. I was actually just looking for a simple for loop command, which I figured out. I came up with this and it works good.

for host in `cat pwords`; do sudo ./passwd_mgr.pl -s $host; done
