How to read a subfolder one by one in parent folder?

1. Use 'find' utility (that seems to be the answer for your question)
2. Imagine a file with name some tricky $name$ with
newline characters
and think how your code would work like... In fact how it would NOT work
3. Try using high level shell (you have not specified whether this is a HTML document or shell code or whatever) like ksh,bash,zsh,etc. Then provide "magic number" in the first line.
4. If using a high level shell - use [[ ]] instead of [ ]
5. I tend to use ksh with $() in place of `` - think about `ls `cat pattern_file`` (you can do $(ls $(cat pattern_file)) )
6. If using ksh - try using print instead of echo
7. Avoid nested code (someone told me that writing a lot of if's is not a bad thing... but some other man told me to avoid if's whenever possible - the second one gave me a good advice while the first one wasted my time)
8. If you are using a high level shell then try using "${var}",'${var}' instead of what you wrote

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
