If you have a file and need to know the package that installed the file on the system then the following procedure using pkgchk should help.

In this example we'll use the which command:-

To find the package which installed it use the pkgchk command with the -l and -p options and the full file path of the file as follows:

# pkgchk -l -p /usr/bin/which
