Answer 1

the files should be renamed/moved from .txt to /foo/.bar.txt

You can use rename utility, e.g.:

rename s/\.txt$/\.txt\.bar/g *.txt

^{Hint: The subsitution syntax is similar to sed or vim.}

Then move the files to some target directory by using mv:

mkdir /some/path
mv *.bar /some/path

To do rename files into subdirectories based on some part of their name, check for:

-p/--mkpath/--make-dirs Create any non-existent directories in the target path.

Testing:

$ touch {1..5}.txt
$ rename --dry-run "s/.txt$/.txt.bar/g" *.txt
'1.txt' would be renamed to '1.txt.bar'
'2.txt' would be renamed to '2.txt.bar'
'3.txt' would be renamed to '3.txt.bar'
'4.txt' would be renamed to '4.txt.bar'
'5.txt' would be renamed to '5.txt.bar'
