Thanks.
I'm illiterate as concerns shell scripting, and I hope to remain so
for ever.

Here's a variant on Feng's script that only starts two extra
processes (The original question, for those who came in late, was
" How to instruct soot to optimize all (unrelated) classes in a
directory? The command should override old classes."):

    #!/bin/bash
    DIR=$1
    shift

    cd $DIR
    classes=`echo *class | sed -e 's/\.class / /g' -e 's/\.class$//'`
    java soot.Main $* $classes

The `...` shell construction executes ... in a subshell, then
substitutes its output in the surrounding text.  There may be
some way to do the text substitutions without starting sed, but I
was too lazy to look for one in the bash man page.
