Answer / sabhapathi

Don't mind my answer is lengthy....
Let file name be employee

name, rollno., salary, grade

cut each of records in each field to temp files as follows:
-----------------------------------------------------------
cut -f1 employee > /sm.tmp.$$
cut -f2 employee > /sn.tmp.$$
cut -f3 employee > /so.tmp.$$
cut -f4 employee > /sp.tmp.$$

Paste them as required in to another file as follows
----------------------------------------------------
paste /sn.tmp.$$ /sm.tmp.$$
paste /sn.tmp.$$ /so.tmp.$$
paste /sn.tmp.$$ /sp.tmp.$$
