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.

Answer 2

You may use rename command.

rename 's/(.*)\./$12./' *.html

or

rename 's/.*\K\./2./' *.html

Answer 3

You can do this:

name1="/folder1/something.test.html"
name2="${name1/%.html/2.html}"
echo "$name2"
#mv "$name1" "$name2"

Output:

/folder1/something.test2.html

.html is being replaced with 2.html at the end of the string.

To go back i.e test2 -> test:

name2="/folder1/something.test2.html"
name1="${name2/%2.html/.html}"
