String formatting using AWK

Hi,
I need to insert a line at a particular line number. I am using the below code:

Code:

sed $REV_LINO_NO" i\\
# $CURRENT_DATE $NAME           Changed pwd for cindy\'s id" file > file1

This code works, but the formatting is not as I expected. For example, I get lines as shown below according to the length of the variable '$NAME'

Code:

# 20100401 Sudha           Changed pwd for cindy's id
# 20100401 Sudhaaaaaa       Changed pwd for cindy's id
# 20100401 Su           Changed pwd for cindy's id

I have to format the line that I am inserting as shown below:

Code:

20100401 Sudha        Changed pwd for cindy's id
20100401 Sudhaaaaaa   Changed pwd for cindy's id
20100401 Su           Changed pwd for cindy's id

i.e I want the 4th feild, "Changed pwd for cindy's id" to start at a fixed place. I tried something with awk as shown below:

Code:

echo hi hellll hi | awk '{printf "# %s %s %30s\n", $1,$2,$3}'

but this does not work as I expect.

Your input will be of great help.

Thanks,
Sugan.

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
