How to remove the last character in each line using vim

Question

I have a file:

12345a 123456b 1234567c 12345678d 123456789e 

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

 12345 123456 1234567 12345678 123456789 

Answer 1

You can use :%s/.\{1}$// to remove 1 character from the end of each line.

Answer 2

Use the command :g :

 :g/^/norm $x 

• ^ matches every line that will work.
• norm is short for normal , before the normal command you want to execute.
• $x move to end of line and delete character in normal mode

Answer 3

:%normal $x

• : puts you in command line mode.
• % is a range representing the entire file
• normal says we run the normal mode command
• $x removes the last character in the string

Some overlap with other answers, but for me this text is read most simply.
