Normally to run `setup_refs` once from command line it's: `python setup_refs.py -n John -f England/London/Hackney/ref -c con/con.cnf`

The program folder (/home/program/) contains:
- setup.refs.py (script)
- ref (folder)
- con (folder) - con.cnf (file)


Code:

cd /home/program/ ;

for fldr in /home/program/ref/* ; do

    echo "Setting up ---> $fldr" ;

    basenm=${fldr##*/} ; new_fldr=${basenm%%_*} ; 

    python /home/program/setup_refs.py -f "$new_$fldr" -n /home/program/ref/"$new_$fldr" -c /home/program/config/config.cnf ; 

    echo "$fldr setup complete" ;

done

echo "Automated setup complete." ;

Can this be done?
Observations:
You use the -n and -f switches inconsistently in the code compared to your example.

In your code you use /home/program/config/config.cnf rather than your required con/con.cnf

You don't need the trailing semicolons at the end of each line in bash or other bourne-derived shellscripts.

If you use:
Code:
cd /home/program/ref
for fldr in *

you don't need the extra step of removing the directory part of the filename. You will, however be in a different directory than the one you start out in (this may be a problem, but you are using full pathnames anyway).

Stupid question: In the above code if there is a folder (file?) named john_smith your code will set the $new_fldr variable to john. What happens to a folder named john?

Another stupid question: Have you tried running that code?

rmf

rmf(1)							      General Commands Manual							    rmf(1)

NAME

       rmf - remove folder (only available within the message handling system, mh)

SYNOPSIS

       rmf [+folder] [-help] [-[no]interactive]

OPTIONS

       Prints  a  list of the valid options to this command.  Asks for confirmation before deleting a folder. By default, rmf deletes a folder and
       its messages without asking for confirmation.  If you specify the -interactive option, rmf asks if you are sure before deleting the folder.
       You are advised to use this option, since when rmf deletes a folder its contents are lost irretrievably.

DESCRIPTION

       The  rmf  command  removes all of the messages within the current folder, and then removes the folder itself. If there are any files within
       the folder which are not part of MH, they are not removed, and an error message is displayed.

       You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and rmf  cannot  find
       the current folder,rmf asks you whether you want to delete +inbox instead.

       If the current folder is removed, it makes +inbox current.

       Note that the rmf command irreversibly deletes messages that do not have other links, so use it with caution.

       If  the	folder	being removed is a sub-folder, the parent folder becomes the new current folder, and rmf tells you that this has happened.
       This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current
       folder from which the list was extracted.

       Using  rmf  to  delete a read-only folder deletes the private sequence and current message information from the file, without affecting the
       folder itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.

PROFILE COMPONENTS

       Path: To determine the user's Mail directory

EXAMPLES

       This example shows how rmf asks for confirmation when the -interactive option is used: % rmf -interactive +test Remove folder "test"? y

FILES

       The user profile.
