Solaris dd already uses oseek= for something else, so different option
names should be chosen. Perhaps ibskip= and obseek= for skipping
before each block (in effect, punning on ibs and iseek and obs and
oseek), and ibskiptail= and obseektail= for skipping after each block.
Or perhaps you can think of better names.
I was thinking to have the following:
bseek=BYTES skip BYTES bytes at start of output\n\
bskip=BYTES skip BYTES bytes at start of input\n\
obseek=M[,N] skip M bytes at start of each output block and N bytes after
ibskip=M[,N] skip M bytes at start of each input block and N bytes after
I found the *tail names too long for day-to-day usage. Perhaps if we could
find a shorter name, I could drop the second numeric argument in favour of
a separate option.
It seems like a reasonable addition to me, though someone would have
to write it. The documentation would be the hard part, I think.
Well, I am in the process of writing some proof-of-concept code right
now. As for the documentation...ehmm...ummm...emm... :-)
