Writing output into different files while processing file using AWK
Hi,

I am trying to do the following using AWK program.
1. Read the input data file
2. Parse the record and see if it contains errors
3. If the record contains errors, then write it into Reject file, else, write into usual output file or display it on the screen

Here is what I have done -
BEGIN {FS=OFS="\n"}
{
fld1 = substr ($0, 1, 10)
fld2 = substr ($0, 11, 15)

if (fld1 == " ")
print "ERR : " fld1 "|" fld2 >> a.reject
else
print "ABC : " fld1 "|" fld2
}

When I execute the above awk, it is not creating a.reject file -- though there are input records with fld1 = blank. Kindly help.

Thanks and Regards,
Vidya

prophet::cli::texteditorcommand

   separator_pattern
       A pattern that will match on lines that count as section separators in record templates. Separator string text is remembered as $1.

   comment_pattern
       A pattern that will match on lines that count as comments in record templates.

   build_separator $text
       Takes a string and returns it in separator form. A separator is a line of text that denotes a section in a template.

   build_template_section header => '=== foo ===' [, data => 'bar']
       Takes a header text string and (optionally) a data string and formats them into a template section.

   try_to_edit template => $tmpl [, record => $record ]
       Edits the given template if possible. Passes the updated template in to process_template (errors in the updated template must be handled
       there, not here).

   handle_template_errors error => 'foo', template_ref => $tmpl_str, bad_template => 'bar', rtype => 'ticket'
       Should be called in "process_template" if errors (usually validation ones) occur while processing a record template. This method prompts
       the user to re-edit and updates the template given by "template_ref" to contain the bad template (given by the arg "bad_template" prefixed
       with the error messages given in the "error" arg. If an errors section already exists in the template, it is replaced with an errors
       section containing the new errors.

       If the template you are editing is not section-based, you can override what will be prepended to the template by passing in the
       "errors_pattern" argument, and passing in "old_errors" if a template errors out repeatedly and there are old errors in the template that
       need to be replaced.

       Other arguments are: "rtype": the type of the record being edited. All arguments except overrides ("errors_pattern" and "old_errors" are
       required.
