Well, what did you expect ?

Not sure if awk allows you to print like that without typing all fields explicitly; maybe you could use the Bash shell:

Code:
$
$
$ cat f4
# 20100401 Sudha           Changed pwd for cindy's id
# 20100401 Sudhaaaaaa       Changed pwd for cindy's id
# 20100401 Su           Changed pwd for cindy's id
$
$ while read hsh num name txt
> do
>   printf "%s %s %-30s %-s\n" $hsh $num $name "$txt"
> done <f4
# 20100401 Sudha                          Changed pwd for cindy's id
# 20100401 Sudhaaaaaa                     Changed pwd for cindy's id
# 20100401 Su                             Changed pwd for cindy's id
$

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       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 {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
