Hello Pareshkp,

Following may help you.

Code:
awk 'NR==1||NR==2{gsub(/p|d.*/,X,$3)} NR==3||NR==4 {gsub(/p.*t\_+/,X,$3);gsub(/\_.*/,Y,$3)} 1'  filename
OR
awk 'NR==1||NR==2{gsub(/p|d.*/,X,$3)} NR==3||NR==4 {gsub(/p.*t\_+|\_.*/,Y,$3)} 1'  filename

Output will be as follows.

Code:
P081 wr1 120 22.8[dB]
P081 wr1 122 23.1[dB]
P149 wr1 10 20.4[dB]
P149 wr1 11 22.4[dB]

Thanks,
R. Singh
