Hi,Eagle

Thanks for your reply. I just tried your command but it failed. It said

-bash: nawk: command not found

it seems like we don't have nawk in our server.

Do you have other idea? can I just use awk?

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 ATTRIBUTES
