Ok, I think I am not clear...sorry about that. Rewind...

Into /etc/profile file there are some variables:

USERHOME=/test
ADMINHOME=/test2

Then if the user me has USERHOME string into it's .profile file, then MYVAR becomes /test

Code:
MYVAR=$(sed -n '/HOME}/s/.*{\(.*HOME\)}.*/\1/p' /home/me/.profile)
echo $MYVAR

Then the result of the echo command will be /test

I need to cd to that /test using the variable :

Code:
MYVAR=$(sed -n '/HOME}/s/.*{\(.*HOME\)}.*/\1/p' /home/me/.profile)
echo $MYVAR
cd $MYVAR

So cd to /test

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

	   1.	  Variable assignment lists preceding the command remain in effect when the command completes.

	   2.	  I/O redirections are processed after variable assignments.

	   3.	  Errors cause a script that contains them to abort.

	   4.	  Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
		  variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file  name  genera-
		  tion are not performed.
