On Solaris, you can use the pkgchk command to find out which package a file belongs to.
To find the package that a file belongs to, use the following command:
pkgchk -l -p /path/to/file
Replace /path/to/file with the path to the file you are interested in. This will show you the package that the file belongs to, along with other information about the package.
If the file belongs to multiple packages, pkgchk will list all of the packages that contain the file.
You can also use the pkginfo command to display information about a package, including the files it contains. To do this, use the following command:
pkginfo -l PKG_NAME
Replace PKG_NAME with the name of the package you are interested in. This will show you a list of the files included in the package.
Note: These commands require root privileges to execute.
