Where do the arrays get their data from? Is it in a file or do you store it in the script?

What does "marked by character x" mean? Like find a line with the specified character at the beginning and only substitute on that particular line? Or all lines following that line? Or all lines with that marking?

Does input.txt need to change on every iteration or can the java program read it on standard input? I would suggest to keep a static file and run each java program on a temporary copy.

Code:
#!/bin/sh

valuearray1="foo bar baz"
valuearray2="ick y poo"

for v1 in $valuearray1; do
  for v2 in $valuearray2; do
    sed -e "/^pos1/s/param1/$v1/" -e "/^pos2/s/param2/$v2/" input.txt >/tmp/input.txt
    java suction /tmp/input.txt
  done
done

NAME
replace - a string-replacement utility SYNOPSIS
replace arguments DESCRIPTION
The replace utility program changes strings in place in files or on the standard input. Invoke replace in one of the following ways: shell> replace from to [from to] ... -- file_name [file_name] ... shell> replace from to [from to] ... < file_name from represents a string to look for and to represents its replacement. There can be one or more pairs of strings. Use the -- option to indicate where the string-replacement list ends and the file names begin. In this case, any file named on the command line is modified in place, so you may want to make a copy of the original before converting it. replace prints a message indicating which of the input files it actually modifies. If the -- option is not given, replace reads the standard input and writes to the standard output. replace uses a finite state machine to match longer strings first. It can be used to swap strings. For example, the following command swaps a and b in the given files, file1 and file2: shell> replace a b b a -- file1 file2 ... The replace program is used by msql2mysql. See msql2mysql(1). replace supports the following options. o -?, -I Display a help message and exit. o -#debug_options Enable debugging. o -s Silent mode. Print less information what the program does. o -v Verbose mode. Print more information about what the program does. o -V Display version information and exit. COPYRIGHT
