RE: Using backticks with (mount):

I ran your program, and the value I got for $! was "no such file or directory". So I tried this program: #!/usr/bin/perl print $!; Sure enough, same error message. Apparently $! starts off defined; I don't know why, and I'd noticed before. So you might just want to start things off with: undef $!;
