boaadm 26331 26260 0 Aug 03 ? 0:00 ftp -n

In the line above, 26331 is the pid of the ftp process, and 26260 is the pid of the parent of the ftp process. Should that parent die, the ppid will switch to 1 and init will become the new parent. Since the ppid is not 1, the parent process has not died.

This means one of two things:

1) You are mistaken and there simply is no script B. Script A itself is invoking ftp. (There may be a script B that does something else and then exits, but it didn't invoke that ftp process.)

2) There was a script B, but instead of running ftp, it did an "exec ftp". The exec command causes the new program to overlay the old one. You can never return from an exec. The old program is gone.

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. CMU
