Combined Text Files With a Delimiter to One line

I'm looking to combined multiple text files with a delimiter and their file name then erase all of the new lines and have everything on one line.

So far I can do this with two different scripts:

find -type f -name '*.txt' -print | while read filename; do echo "±±±±± $filename"; cat "$filename"; done > files.txt; 

and

tr '\n' '开发者_如何学Go ' < files.txt  > desiredoutput.txt

I've tried combining these two with no avail. Any suggestions?

The simplest way to combine them would be to do the tr on each $filename in place of cat:

find -type f -name '*.txt' -print | while read filename
 do echo -n "±±±±± $filename "  # The -n suppresses the \n at the end of the line.
    tr '\n' ' ' < "$filename"
    echo -n ' '  # Add a terminating delimiter
 done > desiredoutput.txt;
