The following should be acceptable answers:

a. This will add mytools for the current shell. At command prompt, type the following and hit "enter": PATH=$HOME/mytools:$PATH

b. This will add mytools for child shells as well. At command prompt, type the following and hit "enter": export PATH=$HOME/mytools:$PATH

c. To make this permanent, so commands in mytools directory are usable upon login to the UNIX shell (bash), just add "export PATH=$HOME/mytools:$PATH" to your .bashrc file. Most .bashrc files already have this statement, so it would just be a matter of modifying it.


The placement within PATH is significant. The shell searches for commands from left to right as you read the directories in PATH. In my example, I've placed mytools before all other directories so it is searched first. I do this for two reasons:
1. I want commands in mytools to be used before a command with the same name that is in another directory. Generally, this is not a problem as I don't intentionally use an existing command name.
2. Even if I don't have duplicate command names, I want my scripts to be found quickly. By listing mytools at the beginning, it is searched first. This may only be saving microseconds or less, but that's the way I want it.

Otherwise, adding mytools at the end of the PATH statement is certainly acceptable.

Hope this helps...

list_child

list child(1m)															    list child(1m)

NAME

       list child - Displays a list of all the child pointers whose names match the specified child name

SYNOPSIS

       cdscp list child child-name [with attribute-name = attribute-value]

ARGUMENTS

       The full name of a specific child pointer.  The last simple name can contain wildcard characters.  The name of a particular attribute.  The
       value of a particular attribute.

DESCRIPTION

       The list child command displays a list of all the child pointers whose names match the specified child name.  The last simple name can con-
       tain  wildcard  characters.   You  can  use  a  with  attribute-name  = attribute-value clause to limit output only to child pointers whose
       attributes have values equal to the specified values.  A space must precede and follow the = (equals sign).

   Privilege Required
       You must have read permission to the directory that stores the child pointer.  If you use a with attribute-name = attribute-value clause in
       the command, you also need read or test permission to the selected child pointers.

NOTE

       This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.

EXAMPLE

       The following command displays a list of all the child pointers named in the /.:/sales directory:

       cdscp> list child /.:/sales/*

			       LIST
			      CHILD   /.../abc.com/sales
