ls

This command provides information about the contents and permissions of files within the file system. The bare command ls will list the files in the current directory. In addition to the many options that can be used with this command, the last element on the command line can be a file or directory specification. Wild cards are appropriate here, so ls m* will list all files in the current directory that begin with m. There are many options that can be used with the ls command. A few of the more useful are:

$\begin{hanging} \item{-l} display listing in the \lq\lq long'' format, giving file ty... ...ize. \item{-r} reverse the order of whatever sort has been chosen. \end{hanging}$

Example:

ls -l /dev/l brw-rw-- 1 root cdrom 24, 0 Jan 17 09:45 /dev/lmscd srw-rw-rw- 1 root root , 0 Jun 8 23:49 /dev/log brw-rw-- 1 root disk 7, 0 Sep 23 1996 /dev/loop0 brw-rw-- 1 root disk 7, 1 Sep 23 1996 /dev/loop1 brw-rw-- 1 root disk 7, 2 Sep 23 1996 /dev/loop2 brw-rw-- 1 root disk 7, 3 Sep 23 1996 /dev/loop3 brw-rw-- 1 root disk 7, 4 Sep 23 1996 /dev/loop4 brw-rw-- 1 root disk 7, 5 Sep 23 1996 /dev/loop5 brw-rw-- 1 root disk 7, 6 Sep 23 1996 /dev/loop6 brw-rw-- 1 root disk 7, 7 Sep 23 1996 /dev/loop7 crw-rw-- 1 root lp 6, 0 Jan 17 09:45 /dev/lp0 crw-rw-- 1 root lp 6, 1 Jan 17 09:45 /dev/lp1

lists all the files in /dev that begin with l and lists them in the long format.
