With archives containing more than 30 files, list of extracted files quickly stops being interesting. I a making a script that extracts a .war archive into a tomcat app folder:

When looking in help for 7z command, I noticed this line:

  -bd: Disable percentage indicator

Well, I would really like to enable percentage indicator and use it instead of insane file list. How would I do it? Something like:

But frankly, one line percentage indicator like bellow would be enough:

Progress: 30%

    unfortunately it seems to not be possible in a clean way superuser.com/questions/702122/… – lese Oct 6 '15 at 14:02
  • @lese So the switch in help is just an error then? – Tomáš Zato Oct 6 '15 at 14:04

    If you don't require 7-zip to be used you could try pv <file> | jar xf /dev/stdin. – Marco Oct 6 '15 at 14:48
  • @Marco Seems that jar is not installed on debian by default... 7zip was. Isn't there another alternative? – Tomáš Zato Oct 6 '15 at 15:27
  • Neither pv, nor jar is installed in a default Debian installation. If you only can use certain tools you should mention that in the question. This task is not easy using arbitrary tools, but if you require only a limited toolset, I doubt there will be many answers. – Marco Oct 6 '15 at 15:44

If you are trying to do this using standard utilities, you are definitely going to have to find a very hacky workaround. Otherwise use whiptail -- http://xmodulo.com/create-dialog-boxes-interactive-shell-script.html or pv -- http://www.ivarch.com/programs/pv.shtml.

You're really using p7zip v9.20, the portable version for Unix. 7zip is a Windows program that has a GUI and command-line operation, its documentation doesn't necessarily always apply to p7zip. v9.20 quite old now (~2011), though there were no new releases until 2015. The distributed man pages are untouched since 2007, even in the latest version.

The portable p7zip v16.02 does have a progress indicator (and -bd does disable it). There doesn't seem to be a Changelog just for the portable version so I can't say when it was added, other than after v9.20.1 which I have confirmed does not have it either.

Otherwise, general purpose solutions include pmonitor (requires lsof) as suggested by Marco, or progress (Linux specific). See also this question for further information: Pipe Viewer - Progress monitor performance consequence (my answer there has a script that shows how you might extract the required information from /proc without extra tools).
