I am trying to create a new file (blank file) with:

dd if=/dev/zero of=file.txt count=10240 bs=10240

I also want to use dialog output --gauge, something like this:

dd if=/dev/zero | pv | dd of=output.dat count=10240 bs=102400 iflag=fullblock | dialog --gauge "testing" 10 70 0

I have also tried variations of:

(pv -n /dev/zero | dd if=/dev/zero of=output.dat  bs=1000M  count=1) | dialog --guage "Creating a file..." 10 70 0

However it doesn't work, is just lets me know when the file is completed.

Thanks.

  • Try unbuffer. – Arkadiusz Drabczyk Jun 18 '18 at 13:47
  • Never knew about unbuffer, but tried it now same result – warhansen Jun 18 '18 at 13:54
  • dialogis not a UNIX command. Please explain what you are interested in. – schily Jun 18 '18 at 14:20

Slightly off-topic, but you can use the status=progress operand in dd and you'll get something like this:

  • dd if=/dev/zero of=/dev/null status=progress count=10240 bs=10240results in: dd: bad argument: "status=progress" – schily Jun 18 '18 at 14:19
  • @schily Then your version of dd doesn't support it. – Tomasz Jun 18 '18 at 14:23
  • If you mention a feature that is not supported by the standard dd then you should name that special dd clone. – schily Jun 18 '18 at 14:32
  • @schily It's a standard GNU on Debian 9. But man dd on my FreeBSD says status is an extension to POSIX. – Tomasz Jun 18 '18 at 14:38
  • So you are not using a standard UNIX implementation. The FreeBSD implementation does not support it as well and other dd implementations (like e.g. sdd) use a different command line argument for that feature since 38 years which is approx., 12 years longer than GNU dd exists. – schily Jun 18 '18 at 14:47

I suggest that you skip dialog and use a 'plain' pv progress view in the command line like so

# dd if=/dev/zero bs=10240 count=102400| bash -c 'pv -s 1g  > /media/sudodus/usbdata/output.dat'
 320MiB 0:00:07 [39,2MiB/s] [=========>                        ] 31% ETA 0:00:15
...
1000MiB 0:00:34 [29,1MiB/s] [===============================>  ] 97%            
102400+0 records in
102400+0 records out
1048576000 bytes (1,0 GB, 1000 MiB) copied, 34,4327 s, 30,5 MB/s

I wrote to a USB pendrive to make things slower and easier to 'see'.
