Hello! I tried adding zeroes to the end of a file using ddrescue, but it failed.
With stock ddrescue 1.17 from Fedora 20: /usr/bin/ddrescue -o 2048 -s 0 /dev/null foo ddrescue: Nothing to do. With locally compiled ddrescue 1.19: /usr/local/bin/ddrescue -o 2048 -s 0 /dev/null foo ddrescue: Empty domain. In either case, the file foo is not extended. "Empty domain" sounds more cryptic than "Nothing to do". I think it's a regression. Yes, I know that I can copy 1 byte from /dev/zero and subtract 1 from the output position, but I don't want any workarounds. I know that I can use dd. But I want to use ddrescue, as I know its options and it's doing the right thing most of the time. I think copying 0 bytes is just fine if the output position is specified. Here's a related but different issue. rm foo ddrescue -o 2048 -s 1 /dev/null foo ls -l foo The resulting file "foo" is 0 bytes long. Apparently, the seek is never performed because /dev/null is empty. I believe the seek should be performed if it's explicitly requested on the command line. -- Regards, Pavel Roskin _______________________________________________ Bug-ddrescue mailing list [email protected] https://lists.gnu.org/mailman/listinfo/bug-ddrescue
