Converting Char to Numeric
HI, Here I have the following output and want to do some mathematical calculation on C2 & C3 column. Code:
c1 c2 c3 c4 c5
l1 1-oct 12:30:01 12:35 abc xyz
l2 1-oct 14:20:01 14:35 def pqr
l3 2-oct 23:50:01 00:05 ghi mno
O/p I need as two column inserted in-between the above o/p. i have 50 records like this. C1 C2 C3 C3-C2 C3(l2) - C3(l1) C4 C5 But when I use SET command it is treating the values as character & I am not able to do any operation. echo `expr $3 - $2` expr: non-numeric argument So do we have any other command which can help me in this process or any cmd by which I can convert it to numeric value.
