Hello everyone,

I'm wondering if there's a way to supress the summary output from dd. I'm
working on a backup script, that encrypts the backups, and after encrypting
overwrites the unencrypted file several times using dd. I've tried to
redirect the output with 2>&1 > /dev/null but it doesn't work. Since I run
the script from the daily_local variable in periodic.conf, and the script
backs up 11 filsystems (ZFS) to separate files, the mail from periodic daily
gets ridiculously long, and most of it being dd summaries.

I guess I could hack the source code of dd, but I'd prefer not to have to.
Has anyone got any ideas?

Thanks in advance and Merry Christmas to all of you,

Rolf Nielsen


Order matters.

dd ...   >/dev/null 2>&1

Thanks Noel. I've never considered using that order before. Probably because first time I saw that construct and had it explained to me, it was ordered the way I had it, and I very rarely have any use for it, so I haven't really noticed that my way was wrong; I usually only redirect stdout if anything at all. Anyway, now it works like a charm. Thanks. :)
