 NAME
      freedisk - recover disk space

 SYNOPSIS
      freedisk [-a n] [-v]

 DESCRIPTION
      The freedisk command is an interactive script that finds and
      optionally removes filesets that do not appear to have been used since
      they were originally installed by swinstall (see swinstall(1M)).
      NOTE: Familiarity with swremove (see swremove(1M)) is required for
      successful use of this tool.

      The freedisk command has two phases, any combination of which can be
      executed or skipped.

      The first phase analyzes the regular files in all filesets to discover
      filesets that have remained unused since installation.  Use the -a
      option to specify a usage time other than ``since installation.''

      Filesets that appear to be entirely unused, but which are dependencies
      of other filesets that are in use, are treated by freedisk as though
      they were ``in use'' and are not presented as candidates for removal.

      At the end of the first phase, the swremove command is invoked
      interactively with the filesets that are candidates for removal
      already selected.	 During the swremove session any, all, or none of
      the pre-selected filesets can be removed.

      The second phase of freedisk optionally removes filesets that are used
      only for building kernels.  These filesets are identified by
      containing a control file named freedisk_rmvbl.  This removal occurs
      regardless of when the filesets were last used.  This phase should be
      executed only if you are sure you will not need to rebuild a kernel
      for any reason.  The interactive interface provides more information
      on this capability.

      You can reload kernel build filesets removed during this phase by
      using /var/adm/sw/krn_rmvd.log as the argument to the -f option of
      swinstall.

    Options
      freedisk supports the following options:

	   -a n		  Check access of files only in the previous n days
			  instead of the default of checking access since
			  the fileset installation date.  The n value should
			  be a positive integer.  It is passed to find (see
			  find(1)) as -atime -n.

	   -v		  Provide very verbose output.	Useful when detailed
			  information is required as to which specific files
			  have been used in each fileset.

			  If you prefer to track the operation of the
			  utility in a scrollable and easily viewable form,
			  redirect the output to a file (see the example
			  below) and use an editor on that file.

 RETURN VALUE
      The following are exit values of freedisk:

	    0	Successful completion.
	    1	One or more critical errors occurred.

 DIAGNOSTICS
      Error messages are self-explanatory.

 EXAMPLES
      Use the verbose option of freedisk to identify individual files used
      in each fileset and keep a copy of the output in a file for later use:

	   /opt/contrib/bin/freedisk -v 2>&gt&gt>&&amp&amp&1 | tee filename

      Find filesets that have not been used in the past 90 days:

	   /opt/contrib/bin/freedisk -a 90

 WARNINGS
      Removing the kernel build filesets in phase two can result in
      unresolved fileset dependencies.	This means that swverify (see
      swverify(1M)) will indicate errors, unless the appropriate options are
      used to ignore missing dependencies.

      Be careful when using the -a n option.  Small values of n might cause
      infrequently used filesets to be discovered as unused.
