Answer 1

For simple string suffix and prefix manipulation, I suggest you familiarize yourself with the shell's standard parameter expansion features ${VAR%suffix_to_remove} and ${VAR#prefix_to_remove}. These will work on any standard sh, not just bash:

test -> test2

for NAME in */*.test.html; do      # NAME is, e.g., "dir/foo.test.html"
  BASENAME=${NAME%.test.html}      # BASENAME is "dir/foo"
  mv "$NAME" "$BASENAME.test2.html";
done

test2 -> test is similar:

  ...
  BASENAME=${NAME%.test2.html}      # strip off .test2.html
  ...

You could also use the standard shell utilities basename and dirname to achieve something similar.
