[root@rhel ~]# info ls
File:, 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.
  Because 'ls' is such a fundamental program, it has accumulated many
options over the years. They are described in the subsections below;
within each section, options are listed alphabetically (ignoring case).
The division of options into the subsections is not absolute, since some
options affect more than one aspect of 'ls''s operation.
  Exit status:
    0 success
1 minor problems (e.g., failure to access a file or directory not
    specified as a command line argument. This happens when listing a
    directory in which entries are actively being removed or renamed.)
    2 serious trouble (e.g., memory exhausted, invalid option, failure
    to access a file or directory specified as a command line argument
    or a directory loop)
