Top Forums Shell Programming and Scripting awk to change value in field according to another Post 303027089 by Don Cragun on Saturday 8th of December 2018 11:38:58 PM

One might note that the script I provided for you in post #11 had file2 and file1 as operands to awk after the awk code operand. The trace output you have shown us for the awk command at the end of post #17 shows that awk is called with only one operand (the awk code as its first and only operand). That code is, as you say, stalling because it is waiting for you to type input into it since it has no file operands specifying what files it is supposed to process!

Clearly, the assumption I stated at the end of post #16 was wrong. I trust that you will fix it.

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
