NAWK question

Hello everybody !!

I just started messing around with NAWK/AWK and I find it very interesting. I was trying to have script that prints only the the different lines (lines that are identical and adjacent, some that are identical and not adjacent, and some that are just different)

I tried direclty using the command line (awk '$1 != previous { print; previous = $1 }' file)

I am trying to do it in a script.

Your help will be appreciated Smilie

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 SEE ALSO
