|
||||||
|
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.
|
||||||
|
.Pp

Force multi-column output; this is the default when output is to a terminal.
|
||||||
|
.It Fl c
|
||||||

|
||||||
|
instead of time of last modification of the file for sorting

Each field has three character positions:

.TH LS 1

.SH NAME
|
|
||||||
ls \- list the contents of a directory
|
|
||||||
.SH SYNOPSIS
|
|
||||||
\fBls\fP [\fB\-acdfghilnpqrstu1ACDFLMRTX\fP] [\fIname\fP...]
|
|
||||||
.SH 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.
|
|
||||||
.PP
|
|
||||||
.B Ls
|
|
||||||
has two sources other then the command line to draw options from, one is
|
|
||||||
the environment variable
|
|
||||||
.B LSOPTS
|
|
||||||
that is scanned for option letters when the output of
|
|
||||||
.B ls
|
|
||||||
is displayed on a terminal. The other is the name of
|
|
||||||
.B ls
|
|
||||||
itself. If
|
|
||||||
.B ls
|
|
||||||
is linked to another name, then all the characters after the l are used as
|
|
||||||
flags too, except that d, f, r, t and x are translated to D, F, R, T and X.
|
|
||||||
Useful links are
|
|
||||||
.BR ll ,
|
|
||||||
.BR lf ,
|
|
||||||
.B lm
|
|
||||||
and
|
|
||||||
.BR lx .
|
|
||||||
.PP
|
|
||||||
Files whose names start with a dot are by default not listed.
|
|
||||||
.PP
|
|
||||||
Note that standard MINIX 3 doesn't have sockets, and
|
|
||||||
.B \-u
|
|
||||||
and
|
|
||||||
.B \-c
|
|
||||||
are no-ops on a V1 file system, since only modified times are stored in V1
|
|
||||||
inodes.
