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 meta‐
       data 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 fre‐
       quently 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 actu‐
	      ally 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 con‐
       sidered	as  the	 full path to an executable on which is to be invoked.
       Lines beginning with a pound character in the file will	be  considered
       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 con‐
       figuration.  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:
