NAME

       swremove -- Remove installed software

SYNOPSIS

       swremove  [-d|-r] [-v] [-t targetfile] \
       [-x option=value]  [-X options_file]  [-W option] \
       [software_selections]  [@targets]

       swremove --cleansh [options] [@targets]

DESCRIPTION

       swremove removes installed software.  swremove is a distributed
       utility.  Neither swremove nor any component of swbis is required on
       the target host, however, the target host must look like a Unix system
       at the shell and command-line utility level.  Remote network
       connections are made by ssh.  Ssh is the default but rsh can be
       selected by a command line option.

       swremove operates on installed software identified by a software
       selection and target.

OPTIONS

       -d

              Specify the target is a distribution.

                     Note:  This is currently not supported by this
                     implementation.


       -f FILE

              Read the list of software selections from FILE.


       -p

              Preview mode, establish contact with target host, however,
              modify nothing.


       -r

              Indicates that the operation is on installed software at a
              location indicated by the the target.

                     Note:  This is the default mode among -d and -r


       -t targetfile

              Specify a file containing a list of targets (one per line).


       -v

              Increment the verbose level.


       -x option=value

              Specify the extended option overriding the defaults file value.


       -X FILE

              Specify the extended options filename, FILE,  overriding the
              default filenames.  This option may be given more then once. If
              the resulting specified value is an empty string then reading of
              any options file is disabled.

       --help

              Show help (Implementation extension)

       -W option[,option,...]

              Specify the implementation extension option.
              Syntax: -W option[=option_argument[,option...]
              Options may be separated by a comma.  The implementation
              extension options may also be given individually using the
              '--long-option[=option_arg]' syntax.


       --allow-ambig

              Allows swremove to act on all matching entries.  Without this
              option a software selection that matches more than one installed
              software entry is an error.


       --sig-level=N

              Specify number of required GPG signatures, N equal to 0 means
              don't require the catalog to be signed.


       --cleansh

              Kill stray or zombied processes that match the pattern ``sh
              -s.*_swbis''.  These may be caused by a distributed utility
              segfaulting or a signal handling defect in the swbis utility.


       -W remote-shell=SHELL

              Defaults File Option: swbis_remote_shell_client

              Defaults File Option: swbis_shell_command
              NAME may be one of "bash", "sh" or "posix" and specifies the
              remote command run by the remote shell.  "posix" is
              'PATH=`getconf PATH` sh -s', "bash" is "/bin/bash -s", "sh" is
              "/bin/sh -s", and "ksh" is "ksh -s".  The default is "posix".

       -W use-getconf
              Opposite of --no-getconf.


       -W source-script-name=NAME
              Write the script that is written into the remote shell's stdin
              to NAME.  This is useful for debugging.

       -W target-script-name=NAME
              Write the script that is written into the remote shell's stdin
              to NAME.  This is useful for debugging.

       software_selections

              Refer to the software objects (products, filesets) using
              software spec syntax. (See sw(5) for syntax).


       target

              Refers to the software_collection where the software selections
              are to be applied.  Allows specification of host and pathname
              where the software collection is located.  A target that
              contains only one part is assumed to be a hostname.  To force
              interpretation as a path, use a absolute path or prefix with
              ':'.


       Source and Target Specification and Logic

            Synopsis:
                 Posix:
                      host[:path]
                      host
                      host:
                      /path  # Absolute path

                 Swbis Extension:
                      [user@]host[:path]
                      [user@]host_port[:path]
                      :path

                 Swbis Multi-hop Target Extension:
                      # ':' is the target delimiter
                   # '_' delimits a port number in the host field

                      [user@]host[@@[user@]host[@@...]][:file]
                      [user@]host_port[@@[user@]host[@@...]][:file]

                      # Using ':', a trailing colon is used to
                      # disambiguate between a host and file.
                   # For Example,
                      :file
                      host:
                      host
                      host:file
                      host:host:
                      host_port:host_port:
                      host:host:file
                      user@host:user@host:
                      user@host:user@host:host:
                      user@host:user@host:file

            A more formal description:

            target : HOST_CHARACTER_STRING ':' PATHNAME_CHARACTER_STRING
                   | HOST_CHARACTER_STRING ':'
                   | HOST_CHARACTER_STRING
                   | PATHNAME_CHARACTER_STRING
                   | ':' PATHNAME_CHARACTER_STRING   # Impl extension
                   ;

              PATHNAME_CHARACTER_STRING must be an absolute path unless
                              a HOST_CHARACTER_STRING is given.  Allowing
                              a relative path is a feature of the swbis
                              implementation.

                       NOTE: A '.' as a target is an implementation
                             extension and means extract in current
                             directory.

                       NOTE: A '-' indicating stdout/stdin is an
                             implementation extension.

                       NOTE: A ':' in the first character indicates a filename.
                             This is an implementation extension.

              HOST_CHARACTER_STRING is an IP or hostname.

           Examples:
              Copy the  distribution /var/tmp/foo.tar.gz at 192.168.1.10
                     swcopy -s /var/tmp/foo.tar.gz @192.168.1.10:/root

                               # as a host, not a file.

   Show the options
         swremove --show-options


EXTENDED OPTIONS

       Extended options can be specified on the command line using the -x
       option or from the defaults file, swdefaults.  Shown below is an actual
       portion of a defaults file which show default values.

   POSIX
       These options are set in the /usr/lib/swbis/swdefaults or the
       ~/.swdefaults on the local (management host, host where swremove is
       invoked).  These files on the target host are not used.


         autoselect_dependencies       = false
         distribution_target_directory = /
         enforce_dependencies          = false
         enforce_scripts               = true
         installed_software_catalog    = var/lib/swbis/catalog/
         logfile                       = /var/log/sw.log
         loglevel                      = 1
         select_local                  = true
         verbose                       = 1


   Swbis Implementation
       These options are set in the /usr/lib/swbis/swbisdefaults or the
       ~/.swbis/swbisdefaults file.


          swremove.swbis_no_getconf = true # true or false
         swremove.swbis_shell_command = posix # {sh|bash|posix|ksh}
         swremove.swbis_no_remote_kill = false # true or false
         swremove.swbis_local_pax_write_command=tar #{pax|tar|star|gtar}
         swremove.swbis_remote_pax_write_command=tar #{pax|tar|star|gtar}
         swremove.swbis_local_pax_read_command=tar #{pax|tar|gtar|star}
         swremove.swbis_remote_pax_read_command=tar #{pax|tar|gtar|star}
         swremove.swbis_local_pax_remove_command=tar
         swremove.swbis_remote_pax_remove_command=tar
         swremove.swbis_remote_shell_client=ssh
         swremove.swbis_forward_agent=True
         swremove.swbis_sig_level=0
         swremove.swbis_enforce_all_signatures=false

RETURN VALUE

       0 if all targets succeeded, 1 if all targets failed or internal error,
       2 if some targets failed and some succeeded.

NOTES

        Multiple ssh-hops is an implementation extension.

REQUISITE UTILITIES

       The swbis distributed utilities require bash, public domain ksh, or
       Sun's /usr/xpg4/bin/sh to be present on the target host.  If the
       swbis_shell_command extended option is set to 'detect' you don't have
       to know which one is present, otherwise you may specify one explicitly.

       A POSIX awk is required, and with the ability to specify several
       thousand bytes of program text as a command argument.  GNU awk  works,
       as does the ATT Awk book awk, and the awk on BSD systems.  See the
       INSTALL file for further details regarding a small issue with the
       OpenSolaris (c.2006) awk.

       GNU Privacy Guard, gpg is required for verification of package
       signatures.

       swremove uses rm and rmdir for file and directory removal.

       Other utilities required to be in $PATH on the remote host are: dd, pax
       (or tar|star|gtar), mkdir, echo, test, sleep, read (if not builtin).

BUGS

       swremove is subject to breakage if a user's account on an intermediate
       (or terminal) host in a target spec is not configured to use a Bourne
       compatible shell. (This breakage may be eliminated by use of the --no-
       getconf option as explained above.) swremove does not support rollback
       if an error occurs during processing.
