Most software provided for a Solaris system comes in a package. Removing an installed package is easy, but any command associated with “removing” is worth your attention.
To remove the installed package SUNWtchrx from a system, run this command as root:
pkgrm SUNWtchrx
You may be asked for confirmation before proceeding. One benefit of using packages is that Solaris keeps up with what files are shared by packages. Removing a package consisting of files shared among other installed packages will not remove the shared files.
