Macaulay2 input file

[DT]

Hello, im quite new to M2, and im wondering how I would go about
starting M2 with a pre-written .m2 file as parameter.
I've tried different variations of these, without success:
$ M2 --input "file"
and
$ M2 "file"

The second form you mention should work. Use "M2 --help" to find out
what the possibilities are. Another way is "M2 <file". If those
possibilities don't work for you, email to me privately the output
that appears on the screen so I can see why you think you had no
success.

Example:

thallium$ echo 'print 100!' > bar.m2
thallium$ M2 bar.m2

Hi,

you say that you have an .m2 file. If your file is foo.m2 you have to
use the ending, i.e.:
$ M2 foo.m2

I got friend to try it on his computer, and he got it to work right
away. So im guessing its something wrong with my installation. Thanks
for the help.

You can also do:
M2 < "file"
Or at M2 command prompt, type:
load "file"
