ls -l command

[Thomas Kopp]

What does the the "D" means,
while listing ls -l?
I know it is called door.
But what does this mean.
Thanks
Thomas

Hi,

I am not getting any D while doing ls -l

i could find only d which is for directory

[Stefan Farrelly]

These are the values shown by ls -l, there is no 'D' there, only 'd' which means directory (or sub directory).

b Block special file
c Character special file
d Directory
l Symbolic link
n Network special file
p Fifo (also called a "named pipe") special file
s Socket
- Ordinary file

The only place I have seen a D entry in the permission list is when you delete the shared memory,queue and semaphores using ipcrm.

check for the man pages of ipcs

Some of these can be converted to capitals if the letter that is hidden by the feature is not set:

l1:/tmp 102 > > xx
l1:/tmp 103 > ll xx
1543 -rw-rw-rw- 1 merijn softwr 0 Feb 7 12:47 xx
l1:/tmp 104 > chmod 1666 xx
l1:/tmp 105 > ll xx
1543 -rw-rw-rwT 1 merijn softwr 0 Feb 7 12:47 xx
l1:/tmp 106 > chmod 1777 xx
l1:/tmp 107 > ll xx
1543 -rwxrwxrwt 1 merijn softwr 0 Feb 7 12:47 xx
l1:/tmp 108 > chmod +s xx
l1:/tmp 109 > ll xx
1543 -rwsrwsrwt 1 merijn softwr 0 Feb 7 12:47 xx
l1:/tmp 110 > chmod -x xx
l1:/tmp 111 > ll xx
1543 -rwSrwSrwT 1 merijn softwr 0 Feb 7 12:47 xx
l1:/tmp 112 >

the 'd' however is not a subject to this change. I'm now curious too.

Enjoy, have FUN! H.Merijn

Hi Thomas,

afaik, it's a solaris file type only:

Solaris uses a STREAMS file, usually /dev/log to route locally generated syslog messages. See the log(7d) driver manual page for more information. Starting with SunOS 5.6 (Solaris 2.5.1) the syslog(3) library contains support for "doors", a superfast and multithreaded IPC mechanism provided by the Solaris Operating Environment. Using a door file - /etc/.syslog_door up to SunOS 5.7, /var/run/syslog_door on SunOS 5.8 and later, the process listening on the syslog_door gets immediate notification upon receipt of a log message.

Rgds, Robin
