Hi

Can I format the output by using awk. I know it is possible thru printf. But I read it somewhere that awk can do this. but remembering the format. Can some one help me out?

Thanks in advance
Shahul

Hi Shahul,

Yup, printf is what you're looking for; check out man 3 printf for the specific format string you need.

Darren.

Hi,

Ex:
awk '{printf("hi00%2.0f \n", NR+9)}

---------------------------
Formatted printouts are of the form printf( "format\n", value1, value2, ... valueN)
e.g. printf("howdy %-8s What it is bro. %.2f\n", $1, $2*$3)
%s = string
%-8s = 8 character string left justified
%.2f = number with 2 places after .
%6.2f = field 6 chars with 2 chars after .
\n is newline
\t is a tab

Hi,

what kind of data do you want to format ?

Numeric integer:
printf("%06d\n", var);
will print integer with leading nulls
Float:
printf("%8.2f\n", var);
will print floating with decimal precision of two.
