Use whatever device is the dvdwriter, /dev/cdrom is a link here to
/dev/hdc.  It could be real or a link on your system.  If there is a
file in /var/log, called dmesg, browse it to see what the writer was
called at boot time discovery and use that.

As to the second error, do you not have the utility sha1sum on that
machine?  If missing, that seems to be a potentially serious security
shortcoming.

If you have md5sum, it can be substituted, but will give different
answers when compared to sha1sum.  Whatever you use, the .iso file, and
the readback from the device should be identical.

Also, make sure the pipe symbol used by the mac is the same as used in
the rest of the *nix world, a vertical bar found by shifting the
backslash key on common keyboards.  Some systems have been known to use
the exclamation point as a substitute but that was microwares os9, on a
TRS-80 Color Computer from 2 decades back.  I still have one, running
at times. :)
