Here are the 3 scripts(FirstScrpt.sh,firstcallScrpt.sh,startProcess.sh) that were running in the server for the past several years.
I understand the way it is written is that for every 1 hour 'firstcallScript.sh' is being called in that it kills the pid of 'startProcess.sh'
and starts again.
2 things I noticed
1. Value of pid.txt never changes if it is being is killed and created every hour.
2. It never runs in the background even when it is run with '&' like (./FirstScrpt.sh &)
FirstScrpt.sh firstCallScript.sh startProcess.sh

PEGASUS-INVOKE(1)PEGASUS-INVOKE(1)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.
SEE ALSO pegasus-kickstart(1)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.
