I was trying to get the temp=2|3|4. So I added sort -u at last, but not getting. it is right way to get using sort -u or any other options are available.

Code:
temp=$(grep "nk1577" $INPUTFILE | awk -F [\]\[] '{split($2, a, " : "); print a[2]}' ORS='|' | sort -u)

No!
Sort is used to sort lines into order.
You requested that there be only one line of output, and the code samples that you have been given provide a single line of output as you requested; so sort will have no affect.

If you would have answered the questions I asked in message #5 in this thread, the volunteers here trying to help you might be able to help you find a solution to your problem instead of trying to patch together something that probably still won't meet your needs.

Please answer the questions I asked earlier so we can help you find a solution will meet your needs.

WRAP-AND-SORT(1)					      General Commands Manual						  WRAP-AND-SORT(1)

NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files SYNOPSIS
wrap-and-sort [options] DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort removes trailing spaces in these files. This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and *.install in the debian directory. OPTIONS
-h, --help Show this help message and exit. -a, --wrap-always Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line. -s, --short-indent Only indent wrapped lines by one space (default is in-line with the field name). -b, --sort-binary-packages Sort binary package paragraphs by name. -k, --keep-first When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to the first package. -n, --no-cleanup Do not remove trailing whitespaces. -d path, --debian-directory=path Location of the debian directory (default: ./debian). -f file, --file=file Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no files are specified. -v, --verbose Print all files that are touched. AUTHORS
wrap-and-sort and this manpage have been written by Benjamin Drung <bdrung@debian.org>. Both are released under the ISC license. DEBIAN
