How to find the package which installed a file

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.

Let’s look at the “which” utility in Solaris and find which package installed the file.

The file path for which is /usr/bin/which

# which which
/usr/bin/which

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
