OS X command line installer track progress I am trying to install an application through command line in OS X. This is what I am trying:

hdiutil attach app.dmg
cd /Volumes/appvolume
installer -pkg app.pkg -target "/"


This works fine, however, I am not able to get an output from the installer command from which I can capture the amount of progress made and the time/amount remaining. I tried the verbose option

installer -verbose -pkg app.pkg -target "/"


But this only prints output like installer: Optimizing system for installed software…....., etc, nothing about progress. But it surely knows about progress, because when I install the app via double clicking, the installer window that pops up shows a deterministic progress bar that progresses gradually and reaches full length when installation is complete.

Any way I can capture the progress status through command line installer as well?
You were close - the option you're looking for is -verboseR:

Usage: installer [-help] [-dominfo] [-volinfo] [-pkginfo] [-allowUntrusted] [-dumplog]
             [-verbose | -verboseR] [-vers] [-config] [-plist]
             [-file &lt;pathToFile&gt;] [-lang &lt;ISOLanguageCode&gt;] [-listiso]
             [-showChoicesXML] [-applyChoiceChangesXML &lt;pathToFile&gt;]
             [-showChoicesAfterApplyingChangesXML &lt;pathtoFile&gt;]
             -pkg &lt;pathToPackage&gt;
             -target &lt;[DomainKey|MountPoint]


Here's installer's output installing a Firefox 43.0.1 .pkg built with AutoPkgr with that flag:

timmay:~ da4$ sudo installer -pkg /Users/da4/Desktop/auto/Firefox-43.0.1.pkg -target / -verboseR

I'm not exactly sure when the -verboseR option was added to OS X's installer, but it's present in 10.9+.
