du from list with du of list total
Hi there

i am relatively new to shell scripting and am stuck. I wrote (and borrowed parts of) a script that will read input from a text file and echo the file name and then give me the du of that file right underneath it in a nice clean way only after telling me the number files on which it will perform these actions. I would like it to also give me the combined du of all of the files in the list. Does anybody know how to do this?

here is my script:

#!/bin/bash
if [ ! $1 ]; then
echo missing arguments\(s\)
echo du-from-list.sh \<works-list\>
exit 1
fi

WORKLIST=$1
WORKSIZE=$du -hs /Volumes/image/$line


echo Total Number of Works
cat /Users/tbrc/scripts/ctc/lists/O1.txt | wc -l
sleep 5

exec 3<&0
exec 0<$WORKLIST
while read line
do

echo $line
du -hs /Volumes/image/$line | awk -F/ '{print $1}'

done
exec 0<&3


exit 0


Ideally i could something like
echo "total du"
and then the command


any help helps.

Thanks,
Movomito

java2html

JAVA2HTML(1)						      General Commands Manual						      JAVA2HTML(1)

NAME

       java2html - generates highlighted html-files from Java or C++ source

SYNOPSIS

       java2html [options] [filename...]

DESCRIPTION

       This  manual  page  documents  how  to  use java2html.  If no arguments are given on the command line of java2html, it reads from stdin and
       writes to stdout.

       If invoked with filenames as arguments java2html will write it's output into new files. Names of output files  are  generated by  appending
       ".html" to the corresponding input filename.

   Installing as a CGI program
       java2html  can  be  installed as a CGI program and convert source files on the fly. In order to set this up for apache the webmaster has to
       add the two lines

	       AddType text/x-java .java
	       Action text/x-java /cgi-bin/java2html

       to the webserver configuration file.  java2html depends on the webserver properly setting environment variable PATH_TRANSLATED to the path-
       name  of  the  source  file.  If java2html has been compiled with option -DCOMPRESSION=1 then it will invoke gzip to compress the generated
       HTML before sending it to the requesting browser. Of course java2html takes care to check if the browser accepts gzip encoding.

   OPTIONS
       --     Interpret all following arguments on the command line as filenames.  This is useful, if you want to convert files beginning  with  a
	      '-'.

       -b filename
	      Insert the file 'filename' after converted data and before HTML footer. See also the -s option.

       -c     Turns off CGI-script detection and HTTP header generation.  This is needed to use java2html as a subcommand in another CGI script.

       -h filename
	      Insert the file 'filename' after the HTML headers and before the converted data. See also the -s option.

       -i     Generate	an index only. This will generate a list of references (HREF's) to the labels that java2html creates for your source file.
	      The references are created as list items (<li>) in an HTML list. Each line has the form
	      <li><a href="#name">prototype()</a></li>
	      so they can be used directly as an index list, or further parsed by another script.
	      If you want the index at the top of the source file, you will need a wrapper script like this one:

		#! /bin/sh
		echo "Content-type: text/html"
		echo ""
		echo "<html>"
		echo "<head><title>$PATH_TRANSLATED</title>"
		echo "<meta name="generator""
		echo "content="`java2html -V`">"
		echo "</head>"
		echo "<body>"
		echo "<h1>Source of $PATH_TRANSLATED</h1>"
		echo "<ul>Structures and functions"
		cat $PATH_TRANSLATED | java2html -isc
		echo "</ul>"
		echo "<hr></hr>"
		cat $PATH_TRANSLATED | java2html -sc
		echo "</body></html>"
		exit

       -n     Number lines and label them with 'line' followed by the line number. Empty lines get no label, but the linecounter will  count  them
	      nevertheless. With this feature you can refer to special lines of code from other parts of the generated file or from external files
	      with a line like this:

	      <A HREF="foo.java.html#line301">Go to line 301</A>

       -s     With this option you can suppress the generation of HTML headers.  This is especially useful together with options -b  file  and	-h
	      file.

       -t title
	      Set the title to 'title'. The default is the filename you converted or "stdin" if reading from stdin. This option is only used if -s
	      is not set.

       -u     Print usage information.

       -w width
	      sets the WIDTH attribute for HTML tag <PRE>. If this option is not used a default of 80 is assumed.  (Currently  most  browsers  are
	      ignoring this attribute).

       -V     reports the version number of java2html.

EXIT STATUS

       java2html returns 0 on success, 1 if input files are not existing/readable, 2 if output files are not creatable/writable, 3 if invoked with
       illegal options and 4 if gzip cannot be invoked.
