How to automatically remove the file extension in a file name

Question

I am trying to make a script in bash that requires the removal of the the file extension from a file name, like the following

original:   something.zip
remov         


        

Answer 1

 f=file.zip
 echo ${f%.zip}

 file

The '%' is a parameter modifier, it means, delete from the right side of the value of the variable whatever is after the '%' char, in this case, the string .zip. You can make this more general to remove any trailing extension, by using a wild card like

 echo ${f%.*}

 file

Answer 2

If you want to remove the from the last period to the end, try this:

$ f=some.thing.zip
$ echo ${f%.*}
some.thing
