Well, your quotes are wrong. You want to substitute the result of
running the "seq" command into the for loop, and to do that you need
to use backquotes (`).
Also, note that the above command is for Bourne shells like bash (the
standard shell in GNU/Linux), and won't work in the csh or tcsh shell.
In any case, this is basic shell programming and has nothing
specifically to do with Meep; you can find lots and lots of tutorials
on Unix shell programming online (and there are plenty of books you
can buy.)
Hope steven can give us some comments about how to write a loop in
the ctl file and
Unix command-line to uqdate the frequency.
See the section "how to write a loop in Scheme" in the manual:
