( #3333=superdoc: print w/replies, xml ) Need Help??

Just add some aliases where it doesn't hurt and it's easy to figure out. (I use a tiny virtual machine for this purpose.)

#!/usr/bin/perl use strict; use warnings; use Dumpvalue; # Core Module, dumps like the debugger my $dumper = new Dumpvalue; my $host = shift; my ($name,$aliases,$addrtype,$length,@addrs) = gethostbyname($host) or + die "Can't resolve $host $!\n"; print "$aliases\n"; $dumper->dumpValue(\$aliases);

My /etc/hosts file

127.0.0.1 localhost tf-laptop my-laptop

Running the above code with the argument localhost yields:

$ perl gethostbyname.pl localhost tf-laptop my-laptop -> 'tf-laptop my-laptop'

$aliases is a string holding the aliases seperated by whitespace.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
