Package: sdd
Version: 1.52-10
Severity: normal
'man dd' on 'ibs=':
% man dd | grep -A 1 -n 'ibs=' | tail -n 2
27: ibs=BYTES
28- read BYTES bytes at a time
In the following two tests 'sdd' behaves exactly like 'dd':
# read one byte from a string
% echo hello | sdd ibs=1 count=1 2> /dev/null | wc -c
1
# read one byte from /dev/null (does nothing)
% sdd if=/dev/null ibs=1 count=1 2> /dev/null | wc -c
0
But '-inull' ignores 'ibs=':
% sdd -inull ibs=1 count=1 2> /dev/null | wc -c
512
# try it with '1w'?
% sdd -inull ibs=1w count=1 2> /dev/null | wc -c
512
Since 'man sdd' implies '-inull' is only a faster version of
'if=/dev/null', this looks like a bug.
If it's not a bug, it ought to be documented. And maybe 'sdd'
should return a non-fatal error or warning to indicate that
'ibs=' won't work:
sdd: caution, the '-inull' option ignores 'ibs='
...or even a fatal error:
sdd: syntax error, '-inull' can't be used with 'ibs='
Hope this helps...
