Shell Programming and Scripting
using AWK printf with userdefine variables

thanks...
but how would i then put a / after the value of PATH which will be between the filename and it's path
it doesn't seem that PATH gets a formating expression since it's comming before the formatting expressions.... bear with me as i'm still learning the nuances of awk...
awk -v PATH="$myvar_path" '{printf( PATH "%s\n",$0)}' mydatafile.dat
i figured out another way too, but a bit more involved
awk '{printf("%s/%s\n","'"${myvar_path}"'",$1)}' mydatafile.dat
this way i was able to insert a / after the value of ${myvar_path}
Thanks again for your time.

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).

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
