How do I delete the last character in each line using vim

Question

I have a file:

12345a 123456b 1234567c 12345678d 123456789e 

How do I delete the last character in each line.
And the file will be

12345 123456 1234567 12345678 123456789 

Answer 1

You could use :%s/.\{1}$// to delete 1 character off the end of each line.
