The debug output is nothing but full path file names followed by my target file name which is.
In general it is usually a good idea to just post the information instead of telling us about it. The reason is: being a newcomer (as per your own admission) you might lack the knowledge of what is vital information and what is not. Show the scripts code (you did that), then run it and copy its output from start to end (ideally along with the return code it produced) here, enclosed in CODEtags, like this:

Here is one more such suggestion: are you sure you want to add always to the file in question? Wouldn't you rather want to start an empty file for every run of the script and then fill the contents of all the other files to this one?
If so, supposing outputarray is an array variable containing path names AND there are no special characters (blanks, tabs, ...) in the file names you can do:
${outputarray[*]} will expand to a list of all the array elements and cat takes an (open-ended) list of filenames to process as arguments. There are some restrictions on this and if the array has several hundreds of entries this method might break eventually (the exact point depending on your systems configuration), but for a handful (anything less than hundred for sure) of filenames this works well.
I tried to cat a file to another user that was logged in, but I received an error message that displayed something like:
%cat funny > /dev/ttyp3
zsh: permission denied: /dev/ttyp3

But it gives the contents of K2 only. How is that ?
2) cat > K1 K2
Above operation takes the contents of... (2 Replies)
