Top Forums Shell Programming and Scripting awk: too many output files created from while loop Post 302712167 by agama on Monday 8th of October 2012 10:02:41 PM

Thanks for running the test -- too painful, if not impossible, to ask to see all of the data Smilie

I didn't see this before...

Code:
 
   if($4 == "d") {
      output_file = "no routes.txt";
        while (getline < "nodata.cfg" > 0) {
        for (i=1; i<=num_fields; i=i+1) gsub(header[i],value[i]);
        print $0 >> output_file;
        }
        close("nodata.cfg")
     next;
 }

You've already processed the record, and using getline you'll read to the end of the file and when you drop into the next block you'll always match because $7 will be nil.

Adding a 'next' will cause awk to read the next record and start over.

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME
colrm -- remove columns from a file SYNOPSIS
colrm [start [stop]] DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read from the standard input. Output is written to the standard output. If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec- ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not zero. Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one. ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7). EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs. SEE ALSO
awk(1), column(1), cut(1), paste(1) HISTORY
The colrm command appeared in 3.0BSD. BSD
August 4, 2004 BSD
