I'm reminded of something from space history... On opening an electronic module for inspection: "My god, this part passed all our tests and it's *garbage*!" Just because it works doesn't mean it's sensible. And if you use "for stuff in `cat file`" all over the place? You've suddenly got something to worry about.

The error's always been possible, but somehow you've never fed it lines with spaces before, and never fed it files larger than you can squeeze into a variable. You've been lucky.

Because $i wasn't quoted, your awk line ends up awk -v token=India and Australia are world champions in cricket '{print token "\t" $0}' token gets the "india" part. The rest of it -- "and", "australia", "are", "world", "champions", "in", and "cricket" -- awk tries to run as scripts or read as files.

I am executing this on diff flavour of unix.....let me know any other way

I just did. Try it, it should work. It should be able to handle files of any size too, where your version will barf on files bigger than a few kilobytes on some systems.

awk: bailing out

If you see this: awk: syntax error near line 1 awk: bailing out near line 1 Chances are you are working on Solaris and you are using standard awk. If so, you need to use /usr/xpg4/bin/awk instead, which is POSIX awk (or nawk if that is not available).

IGAWK(1)							 Utility Commands							  IGAWK(1)

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
