This depends heavily on the shell you are using. Under most (if not
all) Unix shells you can say
my $output = qx{/usr/atria/bin/cleartool lslock lbtype:$dep_lbl 2>/dev/null};
to redirect the file handle 2 (STDERR) to the bit bucket (/dev/null).
A better solution is not to use the qx// operator. The IPC::Open3*
module lets you run a command with complete control over its STDIN,
STDOUT, and STDERR.
