Thanks for the help.

when I used this format like this:
Code:
date -d "12/12/2012" +%s

It's giving me result. But i am not able to give my file name with this format as need to change 2nd date column value into number from each line of my file.
Suppose my file name is File1.csv
I tried this

date -d "$2" +%s File1.csv. But it's not working.
