Cannot run command line scripts in perl or gawk

Tyler_Durden - Thanks for the speedy reply. I have modified the script to use the double quotes and to escape the other double quotes.
The script does work now! Awesome!
I did have a bit of a start when I ran it the first time and got an array that was only 4 rows long by tons of columns. Then I remembered that the "4" in the script referenced the number of rows in the input file so I changed that to 65537 so it would match my input file and voila!
I have to do some more studying on all the switches and get more familiar with perl on the command line. It is a lot like awk or sed. Very useful.
I am going to mess with the gawk script to see if it needs a bit of a tweak too.
Thanks a million - 10000Springs(BC)

Well I worked with this a bit last night to get the gawk script running. I was able to make it work but only if I left out the "sort".
From reading a bit of documentation it appears that there is no sort in gawk, it uses asort instead. Even knowing this I haven't been able to get it to fly yet and running without sorting the output gives totally unusable results.
I tried:
gawk script - gawk "NR<5 {a[$2]=$0;next} {a[$2]=a[$2] FS $NF}END {for (i in a) print a[i]|\"sort -n\"}" inputfilename
so that I have replaced the quotes with double-quotes and escaped the quotes around the 'sort -n' part after the pipe. This did not work.
The only way I could execute with on error was to leave the sort after the pipe out of the script.
I will be looking deeper into the asort function in gawk over the next day or two and will post a fix if I find one.
Does anyone have any tips for an alternate method of preserving the sort order of an input in a gawk script?
Thanks for looking. --10000Springs(BC)

docbook2gjots
DOCBOOK2GJOTS(1) General Commands Manual DOCBOOK2GJOTS(1) NAME
docbook2gjots - Convert a DOCBOOK file to gjots format (on stdout) SYNOPSIS
docbook2gjots [ DOCBOOK-file ] DESCRIPTION
docbook2gjots converts a DOCBOOK XML file into gjots format. docbook2gjots uses gawk(1) to perform the conversion. <preface>, <chapter>, <section>, <sect1>, <sect2>, <sect3> and <sect4> tags are used to define NewEntry and NewFolder boundaries. They should definitely have <title> tags. This is a quick and dirty hack using gawk(1) and does no formal checking of XML or SGML syntax nor does it validate against the DOCBOOK DTD. Consequently, if the syntax of the file is broken the conversion will probably fail. It is intended that a round-trip can be made so that gjots(1) can be used as a tool at all stages of DOCBOOK production - mainly as an out- line processor to help the author organise and order the work. A document may well start its life in gjots(1) as the initial thoughts are marshalled. As the document forms up, it can be converted to DOCBOOK with the following command which automatically adds tags such as <?xml...>, <para> etc: gjots2docbook -b file.gjots >file.xml docbook2pdf file.xml Or, starting with an existing DOCBOOK file: docbook2gjots file.xml >file.gjots In the latter case, the document will already have a lot of DOCBOOK tags so to convert back to docbook, add the -e and -p options: gjots2docbook -b -p -e file.gjots >file.xml docbook2pdf file.xml AUTHOR
