NAME
|
||
ls - list the contents of a directory
|
||
|
||
SYNOPSIS
|
||
ls [-acdfgilqrstu1ACFLMRTX] [name...]
|
||
|
||
DESCRIPTION
|
||
For each file argument, list it. For each directory argument, list its
|
||
contents. The current working directory is listed when no files are
|
||
named. Information is printed multicolumn on terminals, single column if
|
||
the output is redirected. The options control what information is shown
|
||
and how.
|
||
|
||
Ls has two sources other then the commands line to draw options from, one
|
||
is the environment variable LSOPTS and is used only when the output of ls
|
||
is displayed on a terminal. The other is the name of ls itself. If ls
|
||
is linked to another name, then all the characters after the l are used
|
||
as flags too, except that f, r, t and x are translated to F, R, T and X.
|
||
Useful links are ll, lf, lm and lx.
|
||
|
||
Files whose names start with a dot are by default not listed.
|
||
|
||
Note that standard Minix doesn't have symbolic links or sockets and -u
|
||
and -c are no-ops on a V1 file system, since only modified times are
|
||
stored in V1 inodes.
|
||
|
||
OPTIONS
|
||
|
||
-a All entries are listed, even . and ..
|
||
|
||
-c Use inode changed time for sorting, listing or searching.
|
||
|
||
-d Do not list contents of directories, but list the directory itself.
|
||
|
||
-f Do not sort (should also be: treat a file as a directory, but that
|
||
can't be implemented portably).
|
||
|
||
-g Suppress the owner name on a long listing (implies -l).
|
||
|
||
-i I-node number printed in first column.
|
||
|
||
-l Long listing: mode, links, owner, group, size and time. (ls -lC
|
||
uses columns in a wide enough window!)
|
||
|
||
-n Print numerical user and group id's.
|
||
|
||
-q Print nongraphic characters as '?' (default on terminals).

|
||
|
||
|
||
-r Reverse the sort order.
|
||
|
||
-s Give size in kilobytes.
|
||
|
||
-t Sort by time (modified time default), latest first.
|
||
|
||
-u Use last accessed time for sorting, listing or searching.
|
||
|
||
-1 Print in one column.
|
||
|
||
-A List all entries, but not . and .. (This is the default for
|
||
privileged users.)
|
||
|
||
-C Print multicolumn (default on terminals).
|
||
|
||
-F Mark directories with a '/', executables with a '*', UNIX domain
|
||
sockets with a '=' and symbolic links with a '@' behind the name.
|
||
|
||
-L Print the file referenced by a symbolic link instead of the link.
|
||
|
||
-M List mode before name (implies -C).
|
||
|
||
-R List directory trees recursively.
|
||
|
||
-T Group files by type, i.e. regular files together, directories
|
||
together, etc.
|
||
|
||
-X Print crunched mode and size before name (implies -C). Only the rwx
|
||
permissions that its caller has on the file, but they are in upper
|
||
case if the caller owns the file and has given the permission to the
|
||
callers group or other users. The size is listed in bytes (<= 5K),
|
||
or rounded up kilo, mega or gigabytes.

|
||
|
||
BUGS
|
||
Having to type ls -C when viewing files through more(1).
|
||
|
||
Is only portable to systems with the same st_mode (see stat(2)).
|
||
|
||
The LSOPTS variable and the -M, -T and -X flags are not found on other ls
|
||
implementations. (They have there own nonstandard flags.)
