Also, you're still not quoting any of your variables and really should be.


thanks Corona688 for the explanation.
my bad, I didn't explain it clearly.
the requests is pass a value (eg: v$abc) when calling the script, get file directory and file name from master file. (below is sample master file), then go to corresponding directory, rename file (may need split the file as well). below pseudocode is testing code to check I can use variable with "$" sign. yes, there may have more than one files matching. could you please advise the best way to handle multiple matches. thanks in advance


Code:
 sample master
directory, filename
abc, v$abc_nau
abc, v$eee_bxy
cde, v$abc_nau



Code:
 #!/bin/ksh
while read filename
do
if [ -f ${filename}* ]; then
mv ${1}* ${1}_newname
fi
done<masterfile|grep ${1}


command to call the script:
Code:
 ksh scriptname 'v$abc'

show_child

show child(1m)															    show child(1m)

NAME

       show child - Displays attribute information about the specified child pointer

SYNOPSIS

       cdscp show child child-name [attribute-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 an attribute; see Descrip-
       tion for valid attribute names.	The value of a particular attribute.

DESCRIPTION

       The show child command displays the names and values of the  attributes	specified  in  attribute-name.	 You  can  use	a  combination	of
       attributes in a single command. Use a space to separate multiple attributes.  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).

       If you do not supply any attributes, the command displays all attributes and their values.  The following is a description of child pointer
       attributes: Specifies the creation timestamp (CTS) of the specified child pointer.  Specifies the unique identifier  of	the  directory	to
       which  the child pointer refers.  Specifies the address, UUID, and name of a set of clearinghouses where a copy of the child directory ref-
       erenced by the child pointer is located. This attribute also specifies whether the directory in a particular clearinghouse is a	master	or
       read-only replica.  Specifies the timestamp of the most recent update to an attribute of the child pointer.

   Privilege Required
       You  must  have	read  permission  to the child pointer.  If you specify a wildcard child name, you also need read permission to the parent
       directory.

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 all of the attributes and values of the child directory to which the child pointer /.:/admin refers:  cdscp>
       show child /.:/admin

			       SHOW
			      CHILD   /.../abc.com/admin
				 AT   1991-10-15-15:56:01
			    CDS_CTS = 1991-10-15-19:55:52.000000003/08-00-2b-1c-8f-1f
			    CDS_UTS = 1991-10-15-19:55:52.000000006/08-00-2b-1c-8f-1f
		     CDS_ObjectUUID = 6b5362e8-8b1c-11ca-8981-08002b0f79aa
		       CDS_Replicas = :
	       Clearinghouse's UUID = 2ab024a8-8b1a-11ca-8981-08002b0f79aa
			      Tower = ncadg_ip_udp:16.18.16.32
			      Tower = ncacn_ip_tcp:16.18.16.32
		       Replica type = master
	       Clearinghouse's Name = /.../abc.com/Boston_CH
