Dear sirs: I send you a bug report.
# DESCRIPTION Bug in dd: it sends wrong messages to stderr. For example, when I do backups, I see "errors" from dd... that really aren't. # WAY TO REPRODUCE THE BUG A user can execute: partition=$(mount | awk '$2=="on" && $3=="/" {print $1}') sudo dd if="$partition" of=/tmp/copseg.dd count=1 bs=512 >/dev/null and then he sees something like this in his screen: 1+0 records in 1+0 records out 512 bytes (512 B) copied, 0,000129625 s, 3,9 MB/s # EXPECTED RESULTS: The user should see nothing, as there was no error and stdout was redirected to /dev/null.
