Use of "last" and "awk" in a script
Hey Fellows,
I hope someone can provide me some input here. I am using this "last" command in a script along with "awk":

last | $AWK 'NF==10 && $8=="-"'

The above pull out users that look like had login on the servers in the past. However it is also showing login for users whos accounts have been deleted so obviously /var/adm/wtmpx database has some old infomation.

Can someone show me an example where I can use the last command along with awk where I can get output based on last 100 days (or whatever days specify).

Thank in advance and look forward to hearing from someone soon.

Thanks,

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
