I am getting duplicate entry in variable temp for example temp=2|2|3|4|4.
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)

Code:
temp=$(grep "nk1577" $INPUTFILE | awk -F [\]\[] '{split($2, a, " : "); b[a[2]]++} END {for(x in b) {a[n++] = x+0}; asort(a); for(i = 1; i <= n; i++) {print a[i]}}' ORS='|')

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.

Longhand using __builtins__ on OSX 10.7.5, ksh, default terminal.
Code:
#/bin/ksh
# get_vals.sh
ifs_str="$IFS"
IFS="$IFS"'[]'
echo "20140320 00:08:23.846 INFO  [WebContainer : 84] - anything in line
20140320 00:08:23.846 Test  [translate : 589] - Virtual and lab lab anything
20140320 00:08:23.846 Data  [anything : 60] - anything in line
20140320 00:08:23.847 anyting  [anything : 5] - anything in line" > /tmp/file1
temp=""
text=""
while read line
do
	temp=($line)
	text=$text${temp[5]}'|'
done < /tmp/file1
echo "$text"
IFS="$ifs_str"
exit 0

Results:-

EDIT:

Added text="" for fullness.

You can adjust it a little towards the end to have:-
Code:
:
:
:
done < /tmp/file1
text="${text%|}"
echo "$text"
:
:

This will trim off the trailing | if that is what is required.
