ls(1B) SunOS/BSD Compatibility Package Commands ls(1B)NAMEls - list the contents of a directory
SYNOPSIS
/usr/ucb/ls [-aAcCdfFgilLqrRstu1] file...
DESCRIPTION
For each filename that is a directory, ls lists the contents of the
directory; for each filename that is a file, ls repeats its name and
any other information requested. By default, the output is sorted
alphabetically. When no argument is given, the current directory is
listed. When several arguments are given, the arguments are first
sorted appropriately, but file arguments are processed before directo‐
ries and their contents.
Permissions Field
The mode printed under the -l option contains 10 characters interpreted
as follows. If the first character is:
d Entry is a directory.
D Entry is a door.
b Entry is a block-type special file.
c Entry is a character-type special file.
l Entry is a symbolic link.
p Entry is a FIFO (also known as "named pipe") special file.
s Entry is an AF_UNIX address family socket.
− Entry is a plain file.
The next 9 characters are interpreted as three sets of three bits each.
The first set refers to owner permissions; the next refers to permis‐
sions to others in the same user-group; and the last refers to all oth‐
ers. Within each set, the three characters indicate permission respec‐
tively to read, to write, or to execute the file as a program. For a
directory, "execute" permission is interpreted to mean permission to
search the directory. The permissions are indicated as follows:
r The file is readable.
w The file is writable.
x The file is executable.
− The indicated permission is not granted.
The group-execute permission character is given as s if the file has
the set-group-id bit set; likewise the owner-execute permission charac‐
ter is given as s if the file has the set-user-id bit set.
The last character of the mode (normally x or `−') is true if the 1000
bit of the mode is on. See chmod(1) for the meaning of this mode. The
indications of set-ID and 1000 bits of the mode are capitalized (S and
T, respectively) if the corresponding execute permission is not set.
A plus sign (+) appended to the list of permissions indicates that an
ACL is associated with the file.
When the sizes of the files in a directory are listed, a total count of
blocks, including indirect blocks, is printed.
OPTIONS
The following options are supported:
-a Lists all entries; in the absence of this option, entries
whose names begin with a `.' are not listed (except for the
privileged user, for whom ls normally prints even files that
begin with a `.').
-A Same as -a, except that `.' and `..' are not listed.
-c Uses time of last edit (or last mode change) for sorting or
printing.
-C Forces multi-column output, with entries sorted down the col‐
umns; for ls, this is the default when output is to a termi‐
nal.
-d If argument is a directory, lists only its name (not its con‐
tents); often used with -l to get the status of a directory.
-f Forces each argument to be interpreted as a directory and
lists the name found in each slot. This option turns off -l,
-t, -s, and -r, and turns on -a; the order is the order in
which entries appear in the directory.
-F Marks directories with a trailing slash (/), doors with a
trailing greater-than sign (>), executable files with a trail‐
ing asterisk (*), FIFOs with a trailing vertical bar (|), sym‐
bolic links with a trailing at-sign (@), and AF_UNIX address
family sockets with a trailing equals sign (=).
-g For ls, shows the group ownership of the file in a long out‐
put.
-i For each file, prints the i-node number in the first column of
the report.
-l Lists in long format, giving mode, ACL indication, number of
links, owner, size in bytes, and time of last modification for
each file. If the file is a special file the size field will
instead contain the major and minor device numbers. If the
time of last modification is greater than six months ago, it
is shown in the format `month date year'; files modified
within six months show `month date time'. If the file is a
symbolic link, the pathname of the linked-to file is printed
preceded by `—>'.
-L If argument is a symbolic link, lists the file or directory
the link references rather than the link itself.
-q Displays non-graphic characters in filenames as the character
?; for ls, this is the default when output is to a terminal.
-r Reverses the order of sort to get reverse alphabetic or oldest
first as appropriate.
-R Recursively lists subdirectories encountered.
-s Indicate the total number of file system blocks consumed by
each file displayed.
-t Sorts by time modified (latest first) instead of by name.
-u Uses time of last access instead of last modification for
sorting (with the -t option) and/or printing (with the -l
option).
-1 Forces one entry per line output format; this is the default
when output is not to a terminal.
OPERANDS
The following operand is supported:
file A path name of a file to be listed. If the file specified is
not found, a diagnostic message is output on standard error.
USAGE
See largefile(5) for the description of the behavior of ls when encoun‐
tering files greater than or equal to 2 Gbyte ( 2**31 bytes).
FILES
/etc/group to get group ID for `ls -g'
/etc/passwd to get user IDs for `ls -l' and `ls -o'

SEE ALSOls(1), attributes(5), largefile(5)NOTES
NEWLINE and TAB are considered printing characters in filenames.
The output device is assumed to be 80 columns wide.
The option setting based on whether the output is a teletype is unde‐
sirable as `ls -s' is much different than `ls -s | lpr'. On the other
hand, not doing this setting would make old shell scripts which used ls
almost certain losers.
Unprintable characters in file names can confuse the columnar output
options.
