The fact that the command works suggests that the problem is with the Perl interpreter: an "ldmadmin watch" just composes and executes the pqutil(1) command after checking for a running LDM (i.e., "ldmadmin isrunning"). Here's the relevant section of ldmadmin(1): elsif ($command eq "watch") { # monitor incoming products while ($_ = $ARGV[0]) { shift; /^-f/ && ($feedset = shift); } if (!isRunning($pid_file, $ip_addr)) { errmsg("There is no LDM server running"); $status = 1; } else { system("pqutil -r -f \"$feedset\" -w $pq_path"); $status = $?; } } What does the command "ldmadmin isrunning && echo Yes" do when executed by the user gilbert?
