PBS(8) BSD System Manager's Manual PBS(8)NAMEpbs — general helper tool
SYNOPSISpbs [-debug] [-dump_pboard] [-dump_userdefs] [-flush_pboard]
[-flush_userdefs] [-existing_languages] language1 language2 ...
DESCRIPTIONpbs is an agent for the Services menu. It scans for and vends available
Services, to populate the Services 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 ses‐
sion. 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 useful 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 localization 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 infor‐
mation. You can use this to determine which apps are providing Ser‐
vices and where they are located on the filesystem.
-dump_userdefs
Prints the userdef cache of Services information. pbs caches Ser‐
vices 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 Ser‐
vices 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 com‐
plete 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 management to Unicode glyph generation, but
now it only does Services.
