how to remove final “dot” from directory name

问题

A program messed up my directory putting a dot "." on the end of some file and directory names. What is the easiest way to remove them?

I have thought of removing the last character but not all the files/dirs have a dot on the end. Also removing all the dots is a problem, this will make the extension useless.

What I need is a rename to change name.of.the.file.ext. to name.of.the.file.ext and name.of.the.dir. to name.of.the.dir

Thanks!

Go over the files with the dot at the end, rename each if possible (i.e. the target file does not exist).

for file in *. ; do
    [[ -e ${file%.} ]] || mv "$file" "${file%.}"
done
echo Not renamed: *.

There might be a rename utility on your machine that will let you do

rename 's/\.$//' *.

Check man rename
