I have question about awk if someone can help me here. I want to find a string (file has just one row) and then get the position of the column.

let say i have 4 columns

a b c d

Look for b and somehow get the column position in this case b is at $2 script doesn't know what is the position of the column. So if awk or something else can help me to get position of the column.

Thanks in Advance.
