NAME

       prebind - prepare frequently executed programs for faster startup

SYNOPSIS


       file]

       [path-list]

DESCRIPTION

       prepares some frequently executed programs for faster startup using (see fastbind(1)), and updates the IPD database for the modified files.

       Many  frequently used commands such as etc. are so short lived that the program startup time takes up a major part of the total run time of
       each instance.  In user-space, a big chunk of startup time could be spent in the dynamic loader, dld.so(5),  in	resolving  the	references
       among the program and its shared library dependencies.  This startup overhead can be avoided using

       Patch  level  changes  affecting  related  shared  libraries  (e.g. libc) can obsolete the information stored in an executable.	So must be
       invoked after each such change, to ensure consistent levels of performance.

       As writes symbol resolution information into the executable, the metadata of the software product that  provides  the  executable  must	be
       updated to reflect the changes.

       facilitates  the  use of It invokes on some executables known to be frequently used on HP-UX systems and updates the IPD database using see
       swmodify(1M).

       By  default, operates on a pre-defined list of executables.  Users can also specify an alternate list of executables by providing it  in  a
       file or as a path-list on the command line.

       For complete details, refer to the whitepaper at

   Options
       supports the following option:

	      Prints the usage information.

	      Prints a preview of commands that will be invoked, without actually invoking them.

	      Removes	information from the specified (or default) list of executables.

	      Reads the list of executables from
			file.

   Arguments
       can  read  a  list of executables either from the command line or from a file.  Each command-line argument or each line in the file will be
       considered as the full path to an executable on which is to be invoked. Lines beginning with a pound character in the file will be  consid-
       ered as comments and ignored.

WARNINGS

       uses  (see  swlist(1M))	to retrieve software product information and so may take a long time to complete, depending on the system software
       configuration.  It is recommended to be used only after patch changes that may affect executables of interest.

       needs to be run with appropriate privileges as required to write to the executables and to run The executables must be writeable.

RETURN VALUES

       returns the following values:
	      Successful completion.
	      Failure.
		     An error has occurred.

FILES

       By default, acts on the following files:

	      While
	      is yet another frequently used executable that can benefit from it is almost always in use and including	it  in	the  default  list
	      would  generate errors. It is recommended that be run mannually on this executable when it is not in use (such as from a root shell,
	      with no users logged in).

       All these executables depend on and some other similar shared libraries, so it is recommended that be run whenever any of  the  files  men-
       tioned above are changed.
