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'

fs_whereis

FS_WHEREIS(1)						       AFS Command Reference						     FS_WHEREIS(1)

NAME

       fs_whereis - Reports each file server housing a file or directory

SYNOPSIS

       fs whereis [-path <dir/file path>+] [-help]

       fs whe [-p <dir/file path>+] [-h]

DESCRIPTION

       The fs whereis command returns the name of each file server machine that houses the volume containing each directory or file named by the
       -path argument.

OPTIONS

       -path <dir/file path>+
	   Names each AFS file or directory for which to return the host file server machine. Partial pathnames are interpreted relative to the
	   current working directory, which is also the default value if this argument is omitted.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output includes a line for each specified directory or file. It names the file server machine on which the volume that houses the
       specified directory or file resides. A list of multiple machines indicates that the directory or file is in a replicated volume.

       Machine names usually have a suffix indicating their cell membership. If the cell is not clear, use the fs whichcell command to display the
       cell in which the directory or file resides. To display the cell membership of the local machine, use the fs wscell command.

EXAMPLES

       The following example indicates that volume housing the directory /afs/abc.com resides is replicated on both "fs1.abc.com" and
       "fs3.abc.com":

	  % fs whereis -path /afs/abc.com
	  File /afs/abc.com is on hosts fs1.abc.com fs3.abc.com
