info command

info ls
File: coreutils.info, Node: ls invocation, Next: dir invocation, Up: Directory listing

10.1 `ls': List directory contents

The `ls' program lists information about files (of any type, including
directories). Options and file arguments can be intermixed
arbitrarily, as usual.

For non-option command-line arguments that are directories, by
default `ls' lists the contents of directories, not recursively, and
omitting files with names beginning with `.'. For other non-option
arguments, by default `ls' lists just the file name. If no non-option
argument is specified, `ls' operates on the current directory, acting
as if it had been invoked with a single argument of `.'.

By default, the output is sorted alphabetically, according to the
locale settings in effect.(1) If standard output is a terminal, the
output is in columns (sorted vertically) and control characters are
output as question marks; otherwise, the output is listed one per line
and control characters are output as-is.
