| Could it be that the .d means "directory" as opposed to a regular file, so that you can easily see the difference even if your terminal doesn't support colors. |

I always assumed that d stood for daemon, it would be interesting to know who chose it originally. |

| Yes, it means "daemon". Daemon is a program, which runs in the background, and takes care of some particular task. The term is coined from Maxwell's demon. |

| Very nice. First I assumed "dir", too. But then I found even files with an .d-ending. Thanks for that. |

| I believe the .d (note the dot) stands for directory. The d for daemon is more often found without a dot (httpd.conf, ...) |

The only files ending .d on my system are some metapost (LaTeX) files (oh, and some in Portage; but that doesn't count as they don't get installed under those names).

| I'm pretty sure the .d stands for directory - there are some which have nothing to do with daemons, modules.d for example. I'm not sure of the significance of the .d, though. (As someone else said, a d suffix without a dot does generally stand for daemon, though.) |

for example? on my system | Code: | | find /etc/ -name "*.d" -type f |
doesn't find anything, only "-type d" does.

So smarties, if .d stands for directory, why are there files ending with it, or why isn't every directory ending with it?

can anyone name an example for files ending with ".d", at least i can't find none. latex-files don't count, since the extension ".d" can represent a special not-so-famous filetype of a special (sub)project. we are talking about "The meaning of .d in init.d conf.d", as i understand, the ".d"s in /etc/.
and we don't need to denote all directories with ".d", since most of them are unambiguous. i think in the first years of unix programs like init, cron,... had a conf-file and a conf-directory, perhaps the file named /etc/program.conf and the directory named /etc/program.d/. so, if there was possibility of confusion they put the ".d". and please, don't ask why they don't get rid of the ".d" once the possibility of confusion is gone. you will never find 100% logic on a 30 year old system.

if ".d" stands for daemon, what are the daemons controlled and configured by the following directories?
| Code: | /etc/X11/wmsession.d
/etc/env.d
/etc/gnome/panel-config/panel.d
/etc/bash_completion.d
/etc/modules.d
/etc/profile.d
/etc/modules.autoload.d |

There aren't. (Well, OK, some LaTeX metapost stuff, and some files in /usr/portage that are installed into .d directories.)
.d directories are used when there is or could be a file with the same or similar name, to prevent confusion. e.g. /etc/bash_completion{,.d}, /etc/profile{,.d}, /etc/X11/xinit/xinitrc{,.d}.
edit: plasmagunman: exactly, great explanation. Of course the history explains a lot...

| That's so mad and I thought there would be a fast answer . Well though I indeed have files on my system with .d I just think the arguments for .d as a directory-indicator are better. You convinced me and I voted for directory |
