"Man" pages are a handy help when one knows the name of the tool. However, in my old age I often forget the exact name of the tool. It should be possible to list all man pages and sift it trough a "grep" filter and thus find the exact name of the tool that one is trying to recall. For instance, when the partitions have been created with their file systems, reiserfstune is a handy tool that I use to set label (volume) names for the partitions with reiser FS. There is a similar tool for ext3 FS, but what is its name? I remember that it, too, has "tune" in its name. I also know that both of these tools have a "man" page.
My problem is that I do not know of a way to list in CLI names of commands which have "man" pages, so I could then filter the list trough grep.
It surely must be possible and easy. In Konqueror, an entry man:/<start of a name> shows the list of commands with man pages in a drop down list. Since it is done in GUI, it should be possible in CLI.
Actually, with Konqueror I can find the command name for ext3 files, which is "tune2fs", but I would like to know a way to search for it in CLI.
does exactly what I want. Generally it would be better if before answering a question the question was read more thoroughly - I've deliberately did state that the command I was looking for is tune2fs (for ext2/ext3 file systems), so that actually I was not looking for the command, but for a way of finding a command with CLI when only a part of a command is known (or recalled).
Thanks for jolting my memory, Nylex - apropos is indeed the answer.
Apropos and man -k outputs look the same to me now, but if I remember correctly, there can be cases where their outputs differ (the other shows more or less than the other). It can just be me, but I have a picture they're not 100% the same.

That part wasn't there when I read your post the first time and I *did* read the entire thing.
Well, Nylex, we are not going to argue about you reading it all in the first place. Let me just say, that I wrote it once and did not edit it afterwards, so whatever is in my post, it has been there since the first posting. May I suggest that you did not pay attention to what you read?
Anyway, your suggestion was very valuable and I gratefully acknowledge that with a big THANK YOU!
