Hi Annihilannic.

I still could not get the right output.

It doesnt combine the third element until the last line read from the first directory's file.

I modified to be something like below:-
Code:
dirs=(A B C D E); 
files=(file1.txt); 

for file in "${files[@]}"; 
do
     v=$(awk '{print $1,$2}' ${dirs[1]}/$file)
	  
     for dir in "${dirs[@]}"; 
	do 
	    w=$(awk '{print $5 }' $dir/$file)
         
        done
        echo "$v $w" >> ../test.txt
done

But its not working too, Basically i wanted to have 1 1 20(from dir A) 30(from dir B) 40 (from dir C) and 50(from dir D) corresponded with respect to each line.

E.g :-

A/file1.txt
1 1 10
2 2 100
B/file1.txt
1 1 20
2 2 1000

C/file1.txt
1 1 30
2 2 10000

D/file1.txt
1 1 40
2 2 100000

E/file1.txt
1 1 50
2 2 1000000

Output:- 1 1 10 20 30 40 50
2 2 100 1000 10000 100000 1000000

Please advise. Thanks.

rmf

rmf(1mh)																  rmf(1mh)

Name
       rmf - remove folder

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

Description
       The  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 cannot find  the
       current folder, asks you whether you want to delete instead.

       If the current folder is removed, it makes current.

       Note that the 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 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 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.

Options
       -help	 Prints a list of the valid options to this command.

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

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