Hello phamnu,

Those above commands worked for me successfully, I tried them in bash environment. There are few questions/suggestions here as follows.
i- It is always good to mention your O.S details into post, in case you are on a Solaris/SunOS system, change awkto /usr/xpg4/bin/awk , /usr/xpg6/bin/awk , or nawk.
ii- If it is possible for you to paste sample Input into code tags (you could remove confidential data if any in it).

Let me know if you have any queries on same.

Thanks,
R. Singh

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME
       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS
       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION
       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS
       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES
       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
