[tex-k] exit code and --interaction

[Manuel Pégourié-Gonnard]

Hi,

I can't understand why in the following example the exit code is 1 with
--interaction=batchmode while it is not otherwise. Sorry if I'm missing
something obvious.

mpg at roth:~% echo '\\relax hi\n \\bye' | pdftex

 \bye' | pdftexThis is pdfTeXk, Version 3.1415926-1.40.9 (Web2C 7.5.7)
 %&-line parsing enabled.
**entering extended mode
