tag 16409 notabug close 16409 stop You're hitting various type and system limits. In general it's best to keep bs=1 and increase the seek size to get this functionality portably. Newer versions of GNU dd though will handle the count=0 case better and not alloc since: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=8901e010f Note also the truncate command which is a more direct means to get this functionality.
thanks, Pádraig.
