dd test displays error

dd test is displaying error -

dd test

nench.sh: line 164: printf: 2.4e+09: invalid number

    average:    0.00 MiB/s

I should mention this is on a ZFS based fs.

@madyoda Might be either your awk version or locale settings.

Can you send post the output of awk --version, awk 'BEGIN {print 2e12}', awk 'BEGIN {print int(2e12)}', and locale, please?

Also, what OS is this on?

@n-st sure, thanks -

Hmm, I didn't expect Ubuntu to ship with mawk instead of gawk…

I've pushed a workaround in 2e4a578, try again now.

@n-st can confirm it works - thank you very much!
