From 708c7f49eb76a27506ad477dfe0eab43e9cc2f2c Mon Sep 17 00:00:00 2001 From: green Date: Sat, 26 Feb 2000 21:29:44 +0000 Subject: Add iseek= and oseek= aliases for the preexisting skip= and seek= operands. Can _YOU_ tell skip= and seek= apart with 100% accuracy every time? This also seems to make us option-for-option compatible with the Solaris dd(1).
