vim: command for removing semicolon if it is the last character of the line

Question

i am searching for a substitution command in vim for removing every semicolon in a file, if it is the last character of the line.

i already found this command, which toggles a semicolon at the end of the line:

nnoremap ;; :s/\v(.)$/\=submatch(1)==';' ? '' : submatch(1).';'<CR>

Can someone help me out here?

SOLUTION

• the command i was searching for, was part of a little greater cleanup i want to do after saving a file. the complete solution looks like that

Answer 1

nnoremap ;; :%s/;$//<CR>

where pressing ;; in normal mode substitutes all ; at line end (;$) with nothing (//)

Answer 2

The below command will remove the semicolon if it is the last character of the line.

Try the below command using sed,

sed 's/;*$//g' <file1> file2
