Top Forums Shell Programming and Scripting awk can't open file; file merge attempt Post 303023096 by Don Cragun on Tuesday 11th of September 2018 10:00:33 PM

One reason why a utility like awk might see an asterisk and include it in a diagnostic message even though it isn't visible when you cat the script onto your terminal is <backspace> characters in your script file. For example, if what you're seeing on your screen as:
Code:
FileA FileB*> NewFile

actually contained some other text and <backspace>s as in the following:
Code:
FileA FileAB<backspace>* <backspace><backspace><backspace><backspace><backspace><backspace><backspace> B*> NewFile

that would produce the diagnostic message you've shown us from the script you've shown us.

Have you tried using:
Code:
od -bc script_name

to see if there are any invisible characters in your script?

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
