It has a 'which' command, but that works only in the msys shell. If I execute it from a cmd.exe shell it just hangs and renders the cmd shell unresponsive. There are, of course, other msys commands that are independent exe's - and they can be run from any shell.

Here's a perl version of 'which'. But it looks not only in $ENV{PATH} but also in @INC directories. I also created a which.bat file which calls which.pl because I am THAT lazy ;-)
###
use Cwd;
@_ = @ARGV;
my $cwd = getcwd unless $cwd = $ENV{'PWD'};
my $inc = join(";", @INC);
$ENV{'PATH'} = "$ENV{'PATH'};$inc";
$regexp = shift || die "usage: $0 regexp\n";
for $dir (split(/;/,$ENV{'PATH'}))
{
if ($dir =~ /^.*[\\\/]$/)
{
chop($dir);
}
if ($dir =~ /\//)
{
$delim = "\/";
}
else
{
$delim = "\\";
}
opendir(DOT, "$dir") || &cantdo($!);
while ($_ = readdir(DOT))
{
print "${dir}${delim}$_\n" if ($_ =~ /$regexp/i);
}
close(DOT);
}
sub cantdo
{
my $error = shift;
warn "can't opendir : $error\n";
next;
}
