From: Thomas Cort Date: Tue, 29 Oct 2013 18:48:38 +0000 (-0400) Subject: Importing usr.bin/hexdump X-Git-Tag: v3.3.0~712 X-Git-Url: http://zhaoyanbai.com/repos/icons/apache_pb.png?a=commitdiff_plain;h=1e33498f8ca6b050f0a32002ca925d1f0c357a7f;p=minix.git Importing usr.bin/hexdump Replaces commands/hexdump as well as commands/od. No Minix-specific changes were needed. test/testsh2.sh was modified to match the spacing used in the output of the NetBSD od command.
