|
* sup -- Software Upgrade Protocol client process
|
|
|
|
|
*
|
|
|
|
|
* Usage: sup [ flags ] [ supfile ] [ collection ... ]
|
|
|
|
|
*
|
|
|
|
|
* The only required argument to sup is the name of a supfile. It
|
|
|
|
|
* must either be given explicitly on the command line, or the -s
|
|
|
|
|
* flag must be specified. If the -s flag is given, the system
|
|
|
|
|
* supfile will be used and a supfile command argument should not be
|
|
|
|
|
* specified. The list of collections is optional and if specified
|
|
|
|
|
* will be the only collections upgraded. The following flags affect
|
|
|
|
|
* all collections specified.
|
|
|
|
|
*
|
|
|
|
|
* -s "system upgrade" flag
|
|
|
|
|
* As described above.
|
|
|
|
|
*
|
|
|
|
|
* -t "upgrade time" flag
|
|
|
|
|
* When this flag is given, Sup will print the time
|
|
|
|
|
* that each collection was last upgraded, rather than
|
|
|
|
|
* performing actual upgrades.
|
|
|
|
|
*
|
|
|
|
|
* -R "resource pause" flag
|
|
|
|
|
* Sup will not disable resource pausing and will not
|
|
|
|
|
* make filesystem space checks.
|
|
|
|
|
*
|
|
|
|
|
* -N "debug network" flag
|
|
|
|
|
* Sup will trace messages sent and received that
|
|
|
|
|
* implement the Sup network protocol.
|
|
|
|
|
*
|
|
|
|
|
* -P "debug ports" flag
|
|
|
|
|
* Sup will use a set of non-privileged network
|
|
|
|
|
* ports reserved for debugging purposes.
|
|
|
|
|
*
|
|
|
|
|
* -X "crosspatch" flag
|
|
|
|
|
* Sup is being run remotely with a crosspatch.
|
|
|
|
|
* Need to be carefull as we may be running as root
|
|
|
|
|
* instead of collection owner.
|
|
|
|
|
*
|
|
|
|
|
* The remaining flags affect all collections unless an explicit list
|
|
|
|
|
* of collections are given with the flags. Multiple flags may be
|
|
|
|
|
* specified together that affect the same collections. For the sake
|
|
|
|
|
* of convience, any flags that always affect all collections can be
|
|
|
|
|
* specified with flags that affect only some collections. For
|
|
|
|
|
* example, "sup -sde=coll1,coll2" would perform a system upgrade,
|
|
|
|
|
* and the first two collections would allow both file deletions and
|
|
|
|
|
* command executions. Note that this is not the same command as
|
|
|
|
|
* "sup -sde=coll1 coll2", which would perform a system upgrade of
|
|
|
|
|
* just the coll2 collection and would ignore the flags given for the
|
|
|
|
|
* coll1 collection.
|
|
|
|
|
*
|
|
|
|
|
* -a "all files" flag
|
|
|
|
|
* All files in the collection will be copied from
|
|
|
|
|
* the repository, regardless of their status on the
|
|
|
|
|
* current machine. Because of this, it is a very
|
|
|
|
|
* expensive operation and should only be done for
|
|
|
|
|
* small collections if data corruption is suspected
|
|
|
|
|
* and been confirmed. In most cases, the -o flag
|
|
|
|
|
* should be sufficient.
|
|
|
|
|
*
|
|
|
|
|
* -b "backup files" flag
|
|
|
|
|
* If the -b flag if given, or the "backup" supfile
|
|
|
|
|
* option is specified, the contents of regular files
|
|
|
|
|
* on the local system will be saved before they are
|
|
|
|
|
* overwritten with new data. The data will be saved
|
|
|
|
|
* in a subdirectory called "BACKUP" in the directory
|
|
|
|
|
* containing the original version of the file, in a
|
|
|
|
|
* file with the same non-directory part of the file
|
|
|
|
|
* name. The files to backup are specified by the
|
|
|
|
|
* list file on the repository.
|
|
|
|
|
*
|
|
|
|
|
* -B "don't backup files" flag
|
|
|
|
|
* The -B flag overrides and disables the -b flag and
|
|
|
|
|
* the "backup" supfile option.
|
|
|
|
|
*
|
|
|
|
|
* -d "delete files" flag
|
|
|
|
|
* Files that are no longer in the collection on the
|
|
|
|
|
* repository will be deleted if present on the local
|
|
|
|
|
* machine. This may also be specified in a supfile
|
|
|
|
|
* with the "delete" option.
|
|
|
|
|
*
|
|
|
|
|
* -D "don't delete files" flag
|
|
|
|
|
* The -D flag overrides and disables the -d flag and
|
|
|
|
|
* the "delete" supfile option.
|
|
|
|
|
*
|
|
|
|
|
* -e "execute files" flag
|
|
|
|
|
* Sup will execute commands sent from the repository
|
|
|
|
|
* that should be run when a file is upgraded. If
|
|
|
|
|
* the -e flag is omitted, Sup will print a message
|
|
|
|
|
* that specifies the command to execute. This may
|
|
|
|
|
* also be specified in a supfile with the "execute"
|
|
|
|
|
* option.
|
|
|
|
|
*
|
|
|
|
|
* -E "don't execute files" flag
|
|
|
|
|
* The -E flag overrides and disables the -e flag and
|
|
|
|
|
* the "execute" supfile option.
|
|
|
|
|
*
|
|
|
|
|
* -f "file listing" flag
|
|
|
|
|
* A "list-only" upgrade will be performed. Messages
|
|
|
|
|
* will be printed that indicate what would happen if
|
|
|
|
|
* an actual upgrade were done.
|
|
|
|
|
*
|
|
|
|
|
* -k "keep newer files" flag
|
|
|
|
|
* The -k flag, or "keep" supfile option, will cause
|
|
|
|
|
* Sup to check to see whether there is a newer file on
|
|
|
|
|
* the local disk before updating files. Only files
|
|
|
|
|
* which are newer on the repository will be updated.
|
|
|
|
|
*
|
|
|
|
|
* -K "don't keep newer files" flag
|
|
|
|
|
* The -K flag overrides and disables the -k flag and
|
|
|
|
|
* the "keep" supfile option.
|
|
|
|
|
*
|
|
|
|
|
* -l "local upgrade" flag
|
|
|
|
|
* Normally, Sup will not upgrade a collection if the
|
|
|
|
|
* repository is on the same machine. This allows
|
|
|
|
|
* users to run upgrades on all machines without
|
|
|
|
|
* having to make special checks for the repository
|
|
|
|
|
* machine. If the -l flag is specified, collections
|
|
|
|
|
* will be upgraded even if the repository is local.
|
|
|
|
|
*
|
|
|
|
|
* -m "mail" flag
|
|
|
|
|
* Normally, Sup used standard output for messages.
|
|
|
|
|
* If the -m flag if given, Sup will send mail to the
|
|
|
|
|
* user running Sup, or a user specified with the
|
|
|
|
|
* "notify" supfile option, that contains messages
|
|
|
|
|
* printed by Sup.
|
|
|
|
|
*
|
|
|
|
|
* -o "old files" flag
|
|
|
|
|
* Sup will normally only upgrade files that have
|
|
|
|
|
* changed on the repository since the last time an
|
|
|
|
|
* upgrade was performed. The -o flag, or the "old"
|
|
|
|
|
* supfile option, will cause Sup to check all files
|
|
|
|
|
* in the collection for changes instead of just the
|
|
|
|
|
* new ones.
|
|
|
|
|
*
|
|
|
|
|
* -O "not old files" flag
|
|
|
|
|
* The -O flag overrides and disables the -o flag and
|
|
|
|
|
* the "old" supfile option.
|
|
|
|
|
*
|
|
|
|
|
* -v "verbose" flag
|
|
|
|
|
* Normally, Sup will only print messages if there
|
|
|
|
|
* are problems. This flag causes Sup to also print
|
|
|
|
|
* messages during normal progress showing what Sup
|
|
|
|
|
* is doing.

*
|
|
|
|
|
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
|

|
|
|
|
|
*
|
|
|

|
|
|
|
|
* Added -R switch to reenable resource pausing, which is currently
|
|
|
|
|
* disabled by default. Added code to check for free disk space
|

|
|
|
|
|
* system out of disk space as frequently. [V5.19]

|
|
|
|
|
* their root and /usr directory trees. Reversed the order of
|
|
|
|
|
* delete commands to that directories will possibly empty so
|
|
|

|
|
|
|
|
* directory. [V5.13]
