Wow, agama, thanks!

ok, this is my first real use of awk, more or less. here goes:

/_X/ || /_Y/
means search for exactly _X or _Y
print that line, then move onto the next line
then, there is no search term, but you print, then print (effectively printing lines without _X or _Y twice--genius!!!)

THANK YOU!!!

Is there any way to start the awk searching after the first appearance of a string, like the word "matrix"?

Best

Mikey

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).

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
