Solaris file types
As you browse the directories in a Solaris UFS file system, you'll notice many file types. The file type can usually be identified by looking at the first character of the first column of information displayed when issuing the
ls -l command.
A typical listing may look like this when listing the contents of the
# ls -l /etc ls -l /etc total 583 lrwxrwxrwx 1 root root 14 Aug 9 19:18 TIMEZONE -> ./default/init drwxr-xr-x 6 root other 512 Aug 9 20:51 X11 drwxr-xr-x 2 adm adm 512 Aug 10 09:24 acct lrwxrwxrwx 1 root root 14 Aug 9 19:31 aliases -> ./mail/aliases drwxr-xr-x 7 root bin 512 Aug 10 09:34 apache drwxr-xr-x 2 root bin 512 Aug 10 09:26 apache2 drwxr-xr-x 2 root other 512 Aug 9 20:29 apoc -rw-r--r-- 1 root bin 226 Sep 13 14:17 auto_home -rw-r--r-- 1 root bin 248 Aug 9 19:29 auto_master lrwxrwxrwx 1 root root 16 Aug 9 19:18 autopush -> ../sbin/autopush drwxr-xr-x 2 root other 512 Aug 9 20:19 bonobo-activation drwxr-xr-x 2 root sys 512 Aug 9 19:18 certs lrwxrwxrwx 1 root root 18 Aug 9 19:18 cfgadm -> ../usr/sbin/cfgadm lrwxrwxrwx 1 root root 18 Aug 9 20:18 chroot -> ../usr/sbin/chroot : :
The information displayed in the long listing is in the form of columns and is as follows (reading from left to right):
- Ten characters that describe the mode of the file. The first character displays the file type where:
d The entry is a directory. D The entry is a door. l The entry is a symbolic link. b The entry is a block special file. c The entry is a character special file. p The entry is a FIFO (or "named pipe") special file. s The entry is an AF_UNIX address family socket. - The entry is an ordinary file.
- displays the number of links to the file
- displays the file's owner
- displays the file's group
- displays the file size in bytes
- date/time of the file's last modification
- filename (the -> after a file name denotes a symbolic link)
