A reasonable approximation of Everything Search's command line interface, es.exe, under OS X.

es.pl

#!/usr/bin/perl -w

if (@ARGV < 1) {
   print "Usage: es <file glob to search for>\n";
   exit(1);
}

my $nameGlob = shift @ARGV;

exec ('mdfind', qq(kMDItemDisplayName=='${nameGlob}'c), @ARGV) or
    print $STDERR "Couldn't find mdfind: $!";
