Thanks Don, I though that ARGV is GNUmagic.
So my first example should be improved like this
And works nicely with shell wildcards like file*!
BTW most awk versions want if (... ~ "=") instead of if (... ~ /=/), even outside a {block}.
They have a problem to parse the characters ()= within / / but not within " ".

Hi Guys,
I have two files:
f1:

Hi,
Is there anyway to alter this command so that if it does not find a match it will just leave the line alone instead of replacing what it doesn't find with a blank space? (4 Replies)

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS

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
