RE: Output to file

[Dick, Brian E.]

Thanks. Your suggestion pointed me to another solution. I'm running m4
as a command line option to the shell. The shell provides the
redirection.

cmd /c m4 in.file >out.file

Hi Dick!

A wrapper script seems like the easiest way to achieve that, so instead
of
running the real m4, point NAnt at a wrapper script:

$ which m4
/usr/bin/m4
$ cat ./m4
#! /bin/sh
exec >outputfile
/usr/bin/m4 ${1+"$@"}
$ cat ./test.m4
define(`foo', `bar')dnl
foo bar black sheep
$ m4 ./test.m4
bar bar black sheep
$ ./m4 ./test.m4
$ cat outputfile
bar bar black sheep

Error messages alway go to standard error, but will end up on your
console
too, which is probably what you want.

HTH,
