Hammer & Screwdriver Calling is easy, returning info more complicated
To call a script, simply issue the command as you would type it at the normal prompt.

Code:
#script one
echo "hello"
#call second script
good_day
#say good-bye
echo "good-bye"
exit

#script good_day
echo "good day to you"
exit 0

The above are simplified, but hopefully show you the simple logic. The last line of 'exit 0' ends the program and returns an error code of 0.
Before my '#say good-bye' line, I could check for a returned value, with somthing like:
Code:
if [ "$?" -ne 0 ]
   then
      echo "A value was returned"
fi

So, you can pass something back as part of the error-handling ability of master programs and called programs.

Otherwise, the only other effective way I know of to pass data from a called program back to the master program is to write the information to a temporary file.

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
