How could I know the out titles means when use a command? such as "ipcs -m"


How could I know the output titles mean when use a command? such as "ipcs -m"

Since I am not a english speaker,some of the titles(headers) confused me.

Is there any command to check the description of the headers,such as 'man','help'.

thank you.

Thank you.

But I'm looking for a method to sovle the problem thoroughly. "ipcs -m" is only an example.

I hope I can find a way(if any stuff like help docs) to check the descriptions of the headers whatever commonds I use next time.

Thank you.

I think there is no general solution. Some tools are really well documented by man pages, some others may have wiki pages or home pages and some others will remain mysterious forever.

nattch means number of attachments. I suppose it means the number of processes that have mapped the shared memory segment into their address space.

Example of a tool that is really well documented: man top.
