lsdisplays its name as well as any requested, associated information. For each named directory,
lsdisplays the names of files contained within that directory, as well as any requested, associated information.
If no operands are given, the contents of the current directory
are displayed. If more than one operand is given, non-directory operands are
displayed first; directory and non-directory operands are sorted separately
and in lexicographical order. By default,
one entry per line to standard output; the exceptions are to terminals or
-x options are specified.
The options are as follows:
-t) or printing (
-l, except that the owner is not printed.
-loptions are specified.
-soption, causing the sizes to be reported in kilobytes. Overrides any value specified by the
lswrites the name of the link itself and not the file referenced by the link.
-l, but retain user and group IDs in a numeric format. The output of
-ngis identical: a long listing with numerical group ID, and no numerical user ID. The output of
-nlis identical: a long listing with numerical group and user ID.
-n) options is also specified.
-t) or printing (
It is not an error to specify more than one of the following
mutually exclusive options:
-u. Where more than one option is specified from the
same mutually exclusive group, the last option given overrides the others,
-l always overrides
-f always overrides
-noptions are given, the following information is displayed for each file: mode, number of links, owner (though not for
-g), group, size in bytes, time of last modification (“mmm dd HH:MM”), and the pathname. In addition, for each directory whose contents are displayed, the first line displayed is the total number of blocks used by the files in the directory. Blocks are 512 bytes unless overridden by the
If the owner or group name is not a known user or group name,
respectively, or the
-n option is given, the numeric
ID is displayed.
If the file is a character special or block special file, the major and minor device numbers for the file are displayed in the size field.
-T option is given, the time of
last modification is displayed using the format “mmm dd HH:MM:SS
If the file is a symbolic link, the pathname of the linked-to file is preceded by “->”.
The file mode printed under the
-n options consists
of the entry type, owner permissions, group permissions, and other
permissions. The entry type character describes the type of file, as
The next three fields are three characters each: owner permissions, group permissions, and other permissions. Each field has three character positions:
These next two apply only to the third character in the last group (other permissions):
In addition, if the
-o option is
specified, the file flags (see
chflags(1)) are displayed as
comma-separated strings in front of the file size, abbreviated as
BLOCKSIZEis set, and the
-koption is not specified, the block counts (see
-s) will be displayed in units of that size block.
lsdefaults to the terminal width, or 80 columns if the output is not a terminal.
lsutility exits 0 on success, and >0 if an error occurs.
$ ls -l
In addition to listing the contents of the current working directory in long format, show inode numbers, file flags (see chflags(1)), and suffix each filename with a symbol representing its file type:
$ ls -lioF
List the files in /var/log, sorting the output such that the most recently modified entries are printed first:
$ ls -lt /var/log
lsutility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification, except behaviour for the
The flags [
-hT], as well as the
BLOCKSIZE environment variable, are extensions to
The flags [
-go] are marked by
IEEE Std 1003.1-2008 (“POSIX.1”) as
being an X/Open System Interfaces option.
-g flag was used to
specify that the group field be included in long listings. The group field
is now automatically included in the long listing for files and the meaning
