Top Forums Shell Programming and Scripting Modifying awk code to be inside condition Post 302573077 by otheus on Saturday 12th of November 2011 07:47:05 PM

Your approach isn't working because fext is being set before any input lines are seen. Thus, fext is true if and only if the first argument matches a file with the extension "st". It wont matter what the rest of the arguments are. Further, the FNR==NR mechanism works only to distinguish the very first file from the rest. If you add files to the argument list, they will all be processed as if they were the first file read the second time.

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 SEE ALSO
