Without such a check, the > process just bombs. You might look into the llkr command in /systest/ssr_util. It is so handy that we have copied it to /com... One user used it to write a program that opens an edit window and waits for the user to finish editing the file before exiting... /com/xdmc ce @'^1@' while ((^"/com/llkr ^1 >?/dev/null")) do /com/sleep 5 enddo The while loop runs llkr (list locker) against the file. If llkr generates any output on stdout (which it does if the file is locked...) then the expression is true and the process sleep's 5. If not, the script exits. Sincerely, Philip Pokorny Cummins Electronics (That's where I work, not who tells me what to say...) philip@cel.cummins.com P.S. Before SR10, llkr used to be able to tell you which process had the lock. That was real handy for finding out which program to kill to unlock the file. But now at SR10 you can only tell which node has the file locked not which process... (Oh well...) :)
