I'd like to use the option
oflag=append for a
dd operation to append content to a file. This is to increase the size of the underlying file for a loop device in a case where creating a new larger file is too resource intensive.
dd is not the best option for this anyway but is the best I am aware of. Better suggestions welcome!
My CentOS 4.8 X86_64 server is running coreutils 5.2.1. The version of
dd supplied with this version of coreutils doesn't support the
oflag option. No newer version appears present in the official repo.
I notice the latest version of coreutils is 8.5 and assume that somewhere between 5.2.1 and 8.5 the
oflag option was added.
Assuming I need to upgrade coreutils to a version newer than that currently supplied with CentOS 4.8 x86_64:
- Is it safe to upgrade coreutils?
- Which is the minimum version required for
ddto support the
- From where can I get an RPM? I'd prefer not to compile from source.
