PBS(8)                    BSD System Manager's Manual                   PBS(8)

NAME
     pbs -- general helper tool

SYNOPSIS
     pbs [-debug] [-dump_pboard] [-dump_userdefs] [-flush_pboard] [-flush_userdefs] [-existing_languages]
         language1 language2 ...

DESCRIPTION
     pbs is an agent for the Services menu.  It scans for and vends available Services, to populate the Ser-vices Services
     vices menu.

     pbs is NOT related to the pasteboard.  The pasteboard is managed by the pboard agent.

     pbs normally runs the first time Services are needed in any login session.  You may run it manually for
     debugging Services. If run without any options, pbs will scan for changed Services, cache them along
     with their English localization on a private pasteboard, and immediately update the Services menu in
     all running apps. It will also log about any invalid Services declarations in Info.plist. This is use-ful useful
     ful when developing or testing Services, because it immediately applies any changes.

     ServicesMenu.strings files for a localization are loaded only when an app running under that localiza-tion localization
     tion shows the Services menu.  You may pass pbs language codes (e.g. "fr") to cause it to load that
     localization immediately.  You may also pass the flag -existing_languages to reload already loaded
     localizations.

     pbs has additional options that are useful for debugging, in particular the -dump_pboard option. The
     complete list of options is:

     -debug
         Output debugging information regarding what pbs is doing.

     -dump_pboard
         Prints the private pasteboard containing the current Services information.  You can use this to
         determine which apps are providing Services and where they are located on the filesystem.

     -dump_userdefs
         Prints the userdef cache of Services information.  pbs caches Services information in its userdefs
         to avoid scanning the entire system every boot.  Changed apps are still detected via FSEvents, so
         there is no need to flush the userdef cache when installing a new Service.

     -flush_pboard
         Erases the private pasteboard containing Services information.  The next time the Services menu is
         shown, pbs will scan for changed Services and update the pasteboard.

     -flush_userdefs
         Erases the userdef cache.

     -flush
         Equivalent to -flush_pboard and -flush_userdefs, entirely resetting pbs. The next time Services
         information is needed, pbs will do a complete rescan for apps vending Services, and read their
         plist.  Note: this rescan may be very expensive!

HISTORY
     First appeared in NextStep.  pbs has historically had responsibilities that ranged from pasteboard man-agement management
     agement to Unicode glyph generation, but now it only does Services.
