I have the following script:

set DAY=`date +%y%m%d`
set H=`date +%H`
set M=`date +%M`

awk 'NR==1 {printf "MY HEADER WITH TIME STAMP $H \n"} {print $0}' data1> data2

my result is:

MY HEADER WITH TIME STAMP $H
......data information....
......data information....


How can I get is have the time stamp there but not the $H. The $H should the time to be display.

for example: at 10 o'clock I should have:

MY HEADER WITH TIME STAMP 10

Thanks!

You can try something like this:

#!/bin/ksh

DAY=`date +%y%m%d`
H=`date +%H`
M=`date +%M`

nawk 'NR==1 {printf "MY HEADER WITH TIME STAMP '$H' \n"} {print $0}' data1 > data2
