I'm sorry if this is yaFAQ but I don't normally frequent this group.

I'd like to know what is the absolute definitive way to recognise a
Postscript file.

I'm currently using the following method in my interface script under UN*X

head -3 /tmp/$$ | grep %!

It seems to be the only way that does work all the time.
Although I thought that when the previous interface script I wrote used to
look for a %! as the first 2 chars in the incoming file but of course 
Micros*ft Word for Windows stuffed it because it sends a cntrl-D at the
start of the file.

Any pointers would be appreciated.....MarkC.....
