RavinderSingh13,

Thank you! You are correct, I am using a Solaris OS.

Using nawk and /usr/xpg4/bin/awk I get the following, which is closer to what I need, but I still get /db at the end. How can I remove the /db also?

Code:
>echo "DBPATH=/some/path/database/db" | nawk '{sub(/.*=/,X,$0);print}'
/some/path/database/db

>echo "DBPATH=/some/path/database/db" | /usr/xpg4/bin/awk '{sub(/.*=/,X,$0);print}'
/some/path/database/db

>echo "DBPATH=/some/path/database/db" | /usr/xpg6/bin/awk '{sub(/.*=/,X,$0);print}'
ksh: /usr/xpg6/bin/awk:  not found

largefile(5)                                            Standards, Environments, and Macros                                           largefile(5)

NAME

       largefile - large file status of utilities

DESCRIPTION

       A  large file is a regular file whose size is greater than or equal to 2 Gbyte ( 2**31 bytes). A small file is a regular file whose size is
       less than 2 Gbyte.

   Large file aware utilities
       A utility is called large file aware if it can process large files in the same manner as it does small files. A utility that is large  file
       aware is able to handle large files as input and generate as output large files that are being processed. The exception is where additional
       files  are used as system configuration files or support files that can augment the processing. For example, the file utility supports  the
       -m  option  for  an  alternative "magic" file and the -f option for a support file that can contain a list of file names. It is unspecified
       whether a utility that is large file aware will accept configuration or support files that are large files. If a large file  aware  utility
       does  not accept configuration or support files that are large files, it will cause no data loss or corruption upon encountering such files
       and will return an appropriate error.

       The following /usr/bin utilities are large file aware:

       adb           awk           bdiff         cat           chgrp
       chmod         chown         cksum         cmp           compress
       cp            csh           csplit        cut           dd
       dircmp        du            egrep         fgrep         file
       find          ftp           getconf       grep          gzip
       head          join          jsh           ksh           ln
       ls            mdb           mkdir         mkfifo        more

       rmdir         rsh           sed           sh            sort
       split         sum           tail          tar           tee
       test          touch         tr            uncompress    uudecode

       ls            more          mv            rm            sed
       sh            sort          tail          tr

       install       mkfile        mknod         mvdir         swap

       tem.

       chown         from          ln            ls            sed
       sum           touch

       The /usr/bin/cpio and /usr/bin/pax utilities are large file aware, but cannot archive a file whose size exceeds 8 Gbyte - 1 byte.

       The /usr/bin/truss utilities has been modified to read a dump file and display information relevant to large files, such as offsets.

   Large file safe utilities
       A  utility  is called large file safe if it causes no data loss or corruption when it encounters a large file. A utility that is large file
