Second, you don't need to open the same file 300 times to put 300 things in it. Try this:

Code:
# The round brackets put it in a subshell.  You can redirect the output of the subshell instead
# of each individual command inside it.
(
        # You can feed one here-document into cat instead of running echo 9 times.
        # Note that the ending EOF is at the beginning of the line, not indented.  This is
        # important!  Even indenting that will prevent the here-document from ending properly.
        # Also note that variables will work inside a here-document, just like they would inside
        # double-quotes.
        cat <<EOF
Runtimes for servlet 4, 100K structures

Runs where N=10

run1 test_intput.txt -n 4 -t 1000 -l 100 -d t -N 10
EOF

        time ./myProgram.exe -a arguments -i inputFile -o outputFile

        echo

) > test_times.txt

Thanks for the help, I always learn something new here.

I added a few things to the code you posted,
Code:
SIZE=100K
CPDS=10

(
   cat <<EOF
Runtimes for servlet 4, $SIZE structures

Runs where N=$CPDS

run1 test_ActiMol_$SIZE.sdf -n 4 -t 1000 -l 100 -d t -N $CPDS
EOF

   time ./servert.exe -n 4 -t 1000 -l 100 -d t -N $CPDS -i  'test_ActiMol_'$SIZE'.sdf' -o  'test_ActiMol_100K_'$CPDS'N_2.s'

   echo

) > test_times.txt

and this runs without error, but the the time data is still to cout and does not end up in the file. Everything else ends up in test_times.txt as expected.

I will probably end up with a double loop on SIZE and CPDS, but I need to get the single instance working first. I tried adding the same -o filename after the time command, but I still get the -o: command not found error.

libbash

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
