the answers to these questions may well influence the final solution to your problem.

Now, the general solution to your problem is the find-command: basically it produces a list of files, which (see the -exec-clause) then can be subjected to some command. For a (short) introduction see here

I hope this helps.
I am using Ubuntu 12.04 and the shell is the default one that comes with it.


So I have a directory with about 100 folders inside and each of those folders has the following 4 files inside it. I want the script to go into the first folder, look for the files, run the analysis on those files, and then go through the 2nd folder and the 3rd and so on.


I am trying to input those files into this code to automate the analysis instead of having to manually input files using the gui for the program I am using.


Can I just put the script inside the directory with the folder and the text file (with list of folders) and run it from there?

fnext

NEW(1)								     [nmh-1.5]								    NEW(1)

NAME

       new - report on folders with new messages

       fnext - set current folder to next folder with new messages

       fprev - set current folder to previous folder with new messages

       unseen - scan new messages in all folders with new messages

SYNOPSIS

       new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help]

       fnext is equivalent to new -mode fnext

       fprev is equivalent to new -mode fprev

       unseen is equivalent to new -mode unseen

DESCRIPTION

       New  in	its  default  mode  produces  a  one-line-per-folder  listing of all folders containing messages in the listed sequences or in the
       sequences listed in the profile entry "Unseen-Sequence".  Each line contains the folder, the number of messages in the  desired	sequences,
       and the message lists from the .mh_sequences file.  For example:

	    foo     11.* 40-50
	    bar    380.  760-772 824-828
	     total    391.

       The `*' on foo indicates that it is the current folder.	The last line shows the total number of messages in the desired sequences.

       New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order.  Override this behavior by provid-
       ing foldersfile containing the pre-sorted list of folders new should check, one per line.

       In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively.

       In unseen mode, new executes scan sequences for each matching folder.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder
       Unseen-Sequence:     The name of the unseen message sequence

SEE ALSO

       scan(1), mh-format(5)
