remove date from filename but keep the file extension

I have files like these in a directory called current_dir:

my data-file 2014-10.txt
data file201409.txt

and I want

my data-file.txt
data file.txt

Here is what I tried

rename 's/ *[0-9]{4}-?[0-9]{2}.*$//' current_dir/*.txt

but it removed the .txt extension as well.

I'm quite new to linux, could anyone help me?

you can do it in bash. only if you are sure that the date part is right beside .txt extension on the left

cd $current_dir
for file in *.txt
do
  mv "$file" "${file%%[0-9]*.txt}
done

rename only replaces the matched part so removing .*$ from the regular expression keeps the .txt

rename 's/ *[0-9]{4}-?[0-9]{2}//' current_dir/*.txt

Examples

$ rename -n 's/ *[0-9]{4}-?[0-9]{2}//' *.txt
rename(data file201409.txt, data file.txt)
rename(my data-file 2014-10.txt, my data-file.txt)
