### 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
                  Supported shells are "ssh" and "rsh", ssh is the default.

           -W show-options-files
                  Show the complete list of options files and if they are found.

           -W show-options
                  Show the options after reading the files and parsing the command
                  line options.

           -W pax-command={tar|pax|star|gtar}
                  Set the portable archive command for all operations.  The
                  default is "pax".

           -W pax-read-command={tar|pax|star|gtar}
                  Set the read command for local and remote hosts.

           -W remote-pax-read-command={tar|pax|star|gtar}
                  Defaults File Option: swbis_remote_pax_read_command
                  Set the read command for remote hosts.  This is the command that
                  runs on the target (e.g. pax -r, tar xpf -).  The default is
                  "pax".

           -W local-pax-read-command={tar|pax|star|gtar}
                  Defaults File Option: swbis_local_pax_read_command
                  Set the read command for local hosts.  This is the command that
                  runs on the target (e.g. pax -r, tar xpf -).  The default is
                  "pax".

           -W pax-write-command={tar|pax|star|gtar|swbistar}
                  Set the write command for local and remote hosts.  This is the
                  command that runs on the target (e.g. pax -w, tar cf -).

           -W remote-pax-write-command={tar|pax|star|gtar|swbistar}
                  Defaults File Option: swbis_remote_pax_write_command
                  Set the write command for remote hosts.

           -W local-pax-write-command={tar|pax|star|gtar|swbistar}
                  Defaults File Option: swbis_local_pax_write_command
                  Set the portable archive write command for local host
                  operations.  This is the command that runs on the source (e.g.
                  pax -w, tar cf -).  The default is "pax".

           -W remote-pax-write-command={tar|pax|star|gtar|swbistar}

                  Set the portable archive write command for remote host
                  operations.  This is the command that runs on the source (e.g.
                  pax -w, tar cf -).  The default is "pax".

           -W no-defaults
                  Do not read any defaults files.

           -W no-getconf
                  Defaults File Option: swbis_no_getconf
                  Makes the remote command be '/bin/sh -s' instead of the default
                  'PATH=`getconf PATH` sh -s'.

           -W shell-command=NAME
                  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

           Implementation Extension Syntax (multi ssh-hop) :
               Syntax:
               %start   wtarget    # the Implementation Extension Target
                                   # Note: a trailing ':' forces interpretation
                                   # as a host, not a file.
               wtarget   : wtarget DELIM sshtarget
                         | sshtarget
                         | sshtarget DELIM
                         ;
               sshtarget : user '@' target # Note: only the last target
                         | target          # may have a PATHNAME, and only a host
                         ;                 * may have a user
               target   : HOST_CHARACTER_STRING
                        | PATHNAME_CHARACTER_STRING
                        ;
               user     : PORTABLE_CHARACTER_STRING  # The user name

               DELIM    : ':'   # The multi-hop delimiter.
                        ;

### USAGE EXAMPLES

       Remove everything at 192.168.1.2 from the root directory
             swremove --allow-ambig \* @ root@192.168.1.2:/

       Preview removal of every package listing every file, but modify nothing
             swremove -vv -p --allow-ambig \* @ root@192.168.1.2:/

       Remove everything at 192.168.1.2 from the home directory of user
           'jailbird'.
             swremove --allow-ambig \* @ jailbird@192.168.1.2:.

       Remove package foo from the root '/', or elevate your credentials via ssh
             swremove foo @ /
             swremove foo @ root@localhost:/

       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.

                                                                       swremove(8)
