That's odd. I cut the sample to make sure I hadn't introduced a bug transferring it into the edit window, and was able to process the little bit of data that you posted.

The only thing that I can think of that might be causing issues, and I might not see it without your putting the data in code tags, is the position of the leading asterisk. Is it the very first character on the line? If not, that would prevent the script from seeing it as a section marker and thus it wouldn't print anything.

A small change to the first line would handle the case where it was indented by spaces or tabs:

Code:

        /^[ \t]*[*]/ {                            # new section

If the asterisks are the very first character, then it's possible that the awk isn't being executed at all. You can add this line before the 'new section
line in the script to print all input lines to the standard error device as they are read. This will verify that the script is being invoked and the file you think it is parsing is indeed being parsed.

(new line in bold, first few lines after to show placement, but not the whole thing)

Code:

awk '
        {print;}     # debugging -- print everything

        /^[*]/ {                            # new section 
                if( snarf )
                        printf( "\n" );         # terminate the last section
                snarf = 1;                      # open the section
                n = index( $0, "-" );           # find first -
                printf( "%s ", substr( $0, n+1 ) );     # print everything after the first dash
                next;
        }

Have a go with those ideas. Not sure what it could be otherwise.

MAKESH(1)						      General Commands Manual							 MAKESH(1)

NAME

       makeSH - a .SH script maker

SYNOPSIS

       makeSH files

DESCRIPTION

       MakeSH  examines  one or more scripts and produces a .SH file that, when run under sh, will produce the original script.  The .SH script so
       produced has two sections containing code destined for the output.  The first section has variable substitutions performed  on  it  (taking
       values  from  config.sh), while the second section does not.  MakeSH does not know which variables you want to have substituted, so it puts
       the whole script into the second section.  It's up to you to insert any variable substitutions in the first section for any values you want
       from config.sh.

       You  should  run  makeSH from within your top-level directory and use the relative path to the file as an argument, so that the "Extracting
       ..." line printed while running the produced .SH file later on will give that same path.

BUGS

       It could assume that variables from metaconfig's Glossary need to be initialized in the first section, but I'm too lazy to make it do that.
