Here's a shell script I've been using and improving
for the last two years. It executes a series of DOS com-
mands in the current directory, without interfering with
any other active DOSemu processes.
Usage is pretty simple:
dodos 2m << xx
bcc -N -Z -O -ml -I. cbrom.c expand.c compress.c public.c
exitemu
xx
or
echo -e "dir > dosdir\nexitemu" | dodos
The "2m" is optional; it's a new feature that says,
"If DOSemu doesn't finish in two minutes, kill it." It's
very helpful when I want to do an overnight build of 500
BIOS parts, and the 20th one locks up with "Memory allo-
cation error, System Halted".
