The page explains how to match system files and the packages they belong to in Solaris 10.

How to find the Solaris 10 Package a File belongs to?

An example: You want to know which package /usr/ucb/whoami belongs to?

Option 1: Using the pkgchk Command

The pkgchk command will reveil all details about the file-

bash-3.00$ /usr/sbin/pkgchk -l -p /usr/ucb/whoami

NOTE: Couldn't lock the package database.

Pathname: /usr/ucb/whoami

Type: regular file

Expected mode: 0755

Expected owner: root

Expected group: bin

Expected file size (bytes): 5708

Expected sum(1) of contents: 49676

Expected last modification: Jan 23 03:03:26 2005 Referenced by the following packages:

           SUNWscpu

Current status: installed

The note about the non locked database arises from the fact that the command hasn't been called with root privileges.

Option 2: The quick and dirty Approach

The non API way to find a SVR4 package a file belongs to seams to be the system file /var/sadm/install/contents. This is the place Solaris 10 tracks all installed files. Using grep on the file /var/sadm/install/contents is quite comfortable for bulk searches since the pkgchk command takes significant more time.

bash-3.00$ which whoami

/usr/ucb/whoami

bash-3.00$ grep /usr/ucb/whoami /var/sadm/install/contents

/usr/ucb/whoami f none 0755 root bin 5708 49676 1106445806 SUNWscpu

The answer is  SUNWscpu!

bash-3.00$ pkginfo SUNWscpu system SUNWscpu Source Compatibility, (Usr)

The file contents is normally readable by any user. No special privileges are required.

Warning: The file contents is the package database of the system. A corruption of this file will not allow anymore to install packages!
