here is my command.

Code:
$ awk -F\| '{print NF}' abc.txt | sort -u 
5
99
2

Now want to show the record count also as per this delimiter.

Code:
$ awk -F\| '{print NF}' abc.txt | sort | uniq -c 
  2 5
266 99
  5 2

Now i want to print those 5 records which have 2 delimiter.

Please suggest any command here.
According to the data you have shown us above, there are no lines with 2 delimiters. There are 2 lines with 4 delimiters (AKA 5 fields), there are 266 lines with 98 delimiters (AKA 99 fields), and 5 lines with 1 delimiter (AKA 2 fields).

To print the 5 lines with 2 fields, try:
Code:
awk -F'|' 'NF==2' abc.txt

To see that there are no lines with 2 delimiters, try:
Code:
awk -F'|' 'NF==3' abc.txt
