I assume by title, you mean file name ?
I'd probably do something like :
#!/bin/bash
source_dir="/some/path/"
dest_dir="/some/otherpath/"
cd "${source_dir}"
for f in *
do
echo "${f}
" > "${dest_dir}/${f}"
cat "${f}" ) >> "${dest_dir}/${f}"
done
This (apart from any errors I've probably made) should take each file
in the source directory, and echo it's file name and a blank line
followed by it's contents into a new file of the same name in a
different directory.
As Richard Shaw suggests, you could use the "basename" function to
strip off file extensions (eg .txt) if required.
This is one of those jobs where there are multiple ways to do it - a
lot comes down to what tools you are familiar/comfortable with. In my
case Bash, others will suggest Perl, etc, etc.
But assuming you only want to do this once, it's not worth putting a
lot of effort into making it "elegant" - just into making to work.
