OK, I stand corrected. $ /bin/env | wc -c 34664 $ cmd bash: /cygdrive/c/WINNT/system32/cmd: Invalid argument $ strace /bin/env bash: /usr/bin/strace: Invalid argument On the other hand, POSIX would claim that this usage should be failing with E2BIG, not EINVAL. So it looks like Windows does have a hard limit at total environment size of 32k (in spite of their documentation never mentioning it), but that cygwin could do better at reporting the error when trying to invoke a native process. -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
