It's probably not complicated, but, to be frank, you have not done a good job of clearly explaining what you're trying to accomplish.

Even now, we don't know where these different directories that you mention come from. Are they a precompiled list? If so, are they in a file? If not, are they passed to the script as command line parameters? If not, will they be hardcoded into the script? If not a precompiled list, will the code need to walk a hierarchy at runtime to determine what directories currently exist?

You mention 'output results to various path locations'. What does that mean? Are you referring to a stream of data being redirected to a file? Are you referring to using a directory as a location for newly-created files? Are you referring to something else entirely?

What you are trying to do is probably not at all complicated, but the devil is in the details and you've given precious few.

Why not the more direct /aa/bb/cc/myprogram?

Yes. When you source a script (the dot command), the script's commands are run by the current shell, so any changes to the execution environment persist. As for the source of the error message, we'd need to see the code.

PIDOF(8)						Linux System Administrator's Manual						  PIDOF(8)

NAME
pidof -- find the process ID of a running program. SYNOPSIS
pidof [-s] [-c] [-n] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..] DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in /etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead. OPTIONS
-s Single shot - this instructs the program to only return one pid. -c Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be unable to check the current root directory of processes they do not own. -n Avoid stat(2) system function call on all binaries which are located on network based file systems like NFS. Instead of using this option the the variable PIDOF_NETFS may be set and exported. -x Scripts too - this causes the program to also return process id's of shells running the named scripts. -o omitpid Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro- gram, in other words the calling shell or shell script. EXIT STATUS
0 At least one program was found with the requested name. 1 No program was found with the requested name. NOTES
pidof is actually the same program as killall5; the program behaves according to the name under which it is called. When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. Note that that the executable name of running processes is calculated with readlink(2), so symbolic links to executables will also match. SEE ALSO
