Re: Passing string to awk

More universal approach to pass any strings in unix is, e.g.

#!/bin/ksh
env_var="New Year"
year="2004"
awk "
BEGIN{
x=\"${env_var}\";
printf(\"msg: %s\n\",x);

year=\"${year}\";
year++;
printf(\"%ld\n\",year);
exit;
}
"

exit 0 #### EOF Script

I don't really know what you mean by universal, but I don't
think it's well-advised to take this approach. All the escaping
makes things harder to read, and it's quite error-prone. It's
much better to assign values to variables on the awk command-line,
or pass them through the environment.
