If the last ten characters are all on one line,

Code:
sed -n '$s/.*\(..........\)$/\1/p' file

If you might have embedded newlines among those last ten characters, a different approach is needed.

To loop over all files and do each in turn,

Code:
for f in /path/to/directory/*; do
  sed -n '$s/.*\(..........\)$/\1/p' "$f" >"$f".new
done

This will create a new file next to each old file, with the extension ".new" added to the end of the file name.

you said to get last 10 char from a file name, or is it last 10 char of file content? if its file name
Code:
file="testfile1234567890"
echo $file | cut -c10-

if its last 10 char of file content
Code:
tail -c10 filename
