What difference does * make here ? (ls command question)
Solaris 10 (korn shell)

I use -d option with ls command , when I want to suppress contents of the subdirectories being listed
when listing all the directories and files in a directory.

This is what man page says about -d option in ls command.

Code:
 -d           If an argument is a directory, lists  only  its name  (not its contents). 
               Often used with -l to get the status of a directory.

# Creating 2 files and 2 directories for testing

Code:
$ pwd
/tmp/stage_dir
$ ls
$ touch a.txt
$ touch b.txt
$ mkdir mysub_dir1
$ mkdir mysub_dir2
$
$ ls
a.txt       b.txt       mysub_dir1  mysub_dir2

A plain ls -d command will only list just a dot (.) which is understandable because current directory (dot) is just another file and -d option will suppress anything within it from being listed. My question is how the files and directories are listed when an asterik (*) is added . ie. ls -d *




Code:
$ ls -d
.

$ ls -dl
drwxrwxr-x   5 oracle   oinstall     512 Aug  4 23:41 .


$ ls -d *
a.txt       b.txt       mysub_dir1  mysub_dir2
$
$
$
$ ls -ld *
-rw-r--r--   1 oracle   oinstall       0 Aug 26 12:01 a.txt
-rw-r--r--   1 oracle   oinstall       0 Aug 26 12:01 b.txt
drwxr-xr-x   2 oracle   oinstall     512 Aug 26 12:01 mysub_dir1
drwxr-xr-x   2 oracle   oinstall     512 Aug 26 12:01 mysub_dir2

rdup-up

RDUP-UP(1)							       rdup								RDUP-UP(1)

NAME

       rdup-up - update a directory tree with a rdup archive

SYNOPSIS

       rdup-up [OPTION]...  DIRECTORY

DESCRIPTION

       With rdup-up you can update an (possibly) existing directory structure with a rdup archive.

       The rdup archive has to be given to rdup-up's standard input.

   Username and uids
       rdup  outputs  both  the  username  and	uid, the receiving system (which may be a totally different system) checks if the username and uid
       match. If the username and uid don't match the (numeric) uid is used on the file. The same holds true for the groupname and gid.

OPTIONS

       -n     Do a dry-run and do not create anything on disk.

       -t     Create DIRECTORY (ala mkdir -p) if it does not exist.

       -s N   Strip N path components from a pathname. If the resulting pathname is empty after this operation it is skipped. Be  careful  however
	      with the following structure:

		  /foo
		  /foo/bar
		  /foo/bar/bla.txt
		  /foo/blork/bla.txt

	      With rdup-up -s2 this will leave:

		  <empty>
		  <empty>
		  /bla.txt
		  /bla.txt

	      And the last 'bla.txt' will overwrite the previous one, this will happen without warnings.

       -r PATH
	      This option is related to the -s option, but works different. The string PATH is removed from (the beginning of) each pathname. With
	      -r /home/backup the pathname /home/backup/bin/mycmd becomes /bin/mycmd. The same could be done with -s 2, but then you need to count
	      the slashes. Note -s is always performed before -r.

       -v     Be more verbose and echo the processed files to standard output.

       -vv    Be even more verbose and echo processed file and the uid and gid information to standard output.

       -T     Show  a  table  of  contents of the rdup stream received (ala tar -tf -).  With -T the directory argument is optional. -T unsets any
	      verbose (-v) options.

       -h     A short help message.

       -V     Show the version.

EXIT CODE

       rdup-up return a zero exit code on success, otherwise 1 is returned.
