Greetings, The 'ipcs' (and 'ipcrm') command provides information on (or removes some) System V IPC resources. I'd like to know why no similar utility for POSIX IPC has existed for a long time. I would like to know if such a tool exists in case I missed it. If not, I will provide patches to ipcs and ipcrm (or should I separate the functionality into a new utility). Yours sincerely Prasanna Paithankar
