Even more exciting, /usr/bin/tr actually works going the opposite direction, but /usr/ucb/tr doesn't: $ echo x | /usr/bin/tr x '\000' | xxd 0000000: 000a .. $ echo x | /usr/ucb/tr x '\000' | xxd 0000000: 780a x. but other characters seem to work: $ echo x | /usr/ucb/tr x '\012' | xxd 0000000: 0a0a .. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
