NAME

       pegasus-invoke - invokes a command from a file

SYNOPSIS

       pegasus-invoke ( app | @fn ) [ arg | *@fn [..]]

DESCRIPTION

       The pegasus-invoke tool invokes a single application with as many arguments as your Unix
       permits (128k characters for Linux). Arguments are come from two places, either the
       command-line as regular arguments, or from a special file, which contains one argument per
       line.

       The pegasus-invoke tool became necessary to work around the 4k argument length limit in
       Condor. It also permits to use arguments inside argument files without worry about shell,
       Condor or Globus escape necessities. All argument file contents are passed as is, one line
       per argument entry.

ARGUMENTS

       -d
           This option increases the debug level. Currently, only debugging or no debugging is
           distinguished. Debug message are generated on stdout . By default, debugging is
           disabled.

       -h
           This option prints the help message and exits the program.

       --
           This option stops any option processing. It may only be necessary, if the application
           is stated on the command-line, and starts with a hyphen itself.The first argument must
           either be the application to run as fully-specified location (either absolute, or
           relative to current wd), or a file containing one argument per line. The PATH
           environment variables is not used to locate an application. Subsequent arguments may
           either be specified explicitely on the commandline. Any argument that starts with an
           at (@) sign is taken to introduce a filename, which contains one argument per line.
           The textual file may contain long arguments and filenames. However, Unices still
           impose limits on the maximum length of a directory name, and the maximum length of a
           file name. These lengths are not checked, because pegasus-invoke is oblivious of the
           application (e.g. what argument is a filename, and what argument is a mere string
           resembling a filename).

RETURN VALUE

       The pegasus-invoke tool returns 127, if it was unable to find the application. It returns
       126, if there was a problem parsing the file. All other exit status, including 126 and
       127, come from the application.

EXAMPLE

           $ echo "/bin/date" > X
           $ echo "-Isec" >> X
           $ pegasus-invoke @X
           2005-11-03T15:07:01-0600

       Recursion is also possible. Please mind not to use circular inclusions. Also note how
       duplicating the initial at (@) sign will escape its meaning as inclusion symbol.

           $ cat test.3
           This is test 3

           $ cat test.2
           /bin/echo
           @test.3
           @@test.3

           $ pegasus-invoke @test.2
           This is test 3 @test.3

RESTRICTIONS

       While the arguments themselves may contain files with arguments to parse, starting with an
       at (@) sign as before, the maximum recursion limit is 32 levels of inclusions. It is not
       possible (yet) to use stdin as source of inclusion.

HISTORY

       As you may have noticed, pegasus-invoke had the name invoke in previous incantations. We
       are slowly moving to the new name to avoid clashes in a larger OS installation setting.
       However, there is no pertinent need to change the internal name, too, as no name clashes
       are expected.
