Implied double loop - bash 4 needed:
Code:
eval printf "%s\\\n" {$(sed -n '1h; 1!H; ${g;s/\n/,/g; p; }' file1)}\" \"{$(sed -n '1h; 1!H; ${g;s/\n/,/g; p; }' file2)}
folder1 Tom
folder1 Harry
folder1 Sally
folder1 Joe
folder2 Tom
folder2 Harry
folder2 Sally
folder2 Joe
folder3 Tom
folder3 Harry
folder3 Sally
folder3 Joe

Beware of the evil eval for the usual, well known reasons...

Still getting the same error. Here is the output I am getting with that:

Code:
{P.P..Pfolders.txtProups.txt} {P.P..Pfolders.txtProups.txt}

Here is my script currently, the list of folders is being added to an XML file, and i need to add groups too. take a look (Bold is what I need to add):

Code:
		   while read line
			   do
			   folder=${line%}
		       echo "<folder name = \"$folder\" group name = \"$group\">" >> output.xml
			   echo "</folder>" >> output.xml
		    done < folders.txt

This is AIX by the way

I think I may be overthinking this. I divided this into two seperate loops:

Code:
while read line
do
group=${line%}
echo "<group=\"$group\">" >> Output.xml
done < groups.txt


while read line
do
group=${line%}
echo "<group=\"$group\">" >> Output.xml
done < groups.txt

My output looks as expected:

Code:
<folder name = "Folder3">
</folder>
<folder name = "Folder2">
</folder>
<folder name = "Folder1">
</folder>
<folder name = "Folder0">
</folder>
<file group="TestGroup3">
</file>
<file group="TestGroup2">
</file>
<file group="TestGroup1">
</file>

Now, I need to get each of those 3 groups after the start and end tag of folder..

wouldn't it be easier in awk:
Code:
awk 'FNR==NR {f[$0];next} {for (i in f) print i,$0}' folderFile userFile

Yeah, I have played with a few things in awk and sed but I cannot get a viable solution.

where in that snippet that you provided would I place where I want to place the inserted line?

Currently have:

Code:
<folder name = "Folder3">
</folder>



Need:

Code:
<folder name = "Folder3">
    <file group="TestGroup1">
    </file>
</folder>



Thanks!

how about:
Code:
awk -v qq='"' '
   FNR==NR {u[$0];next}
  {
      printf("<folder name = %s%s%s>\n",qq,$0,qq)
      for (i in u) 
         printf("\t<file group =%s%s%s></file>\n",qq,i,qq)
      print "</folder>"
  }' userFile.txt folderFile.txt

Looks like that works, help is much appreciated to everyone in this post that helped me!! Smilie
