If I understand what you are asking, I think the question you want to ask is "How do I assign the output of a command to a shell variable?" The answer to that question is to use the back-quotes around the command and assign it to a variable. For example

Code:
MYDATE=`date`   # puts the output of the date command into variable MYDAY
LOCATION=`pwd` # puts complete path to current directory in LOCATION
USERSONLINE = `wc | who)  - (number of header lines from who)  # count of users

The list of a directory can be acted upon using some like:

Code:
For i in `ls` ; do
{
   ... bunch of code...
}
done

Your syntax will very depending on what shell you are using.

Hopes this gives you some direction on what to look at...

pwd

PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME

     pwd -- return working directory name

SYNOPSIS

     pwd [-L | -P]

DESCRIPTION

     The pwd utility writes the absolute pathname of the current working directory to the standard output.

     Some shells may provide a builtin pwd command which is similar or identical to this utility.  Consult the builtin(1) manual page.

     The options are as follows:

     -L      Display the logical current working directory.

     -P      Display the physical current working directory (all symbolic links resolved).

     If no options are specified, the -L option is assumed.

ENVIRONMENT

     Environment variables used by pwd:

     PWD  Logical current working directory.

EXIT STATUS

     The pwd utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     builtin(1), cd(1), csh(1), sh(1), getcwd(3)

STANDARDS

     The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

BUGS

     In csh(1) the command dirs is always faster because it is built into that shell.  However, it can give a different answer in the rare case
     that the current directory or a containing directory was moved after the shell descended into it.

     The -L option does not work unless the PWD environment variable is exported by the shell.
