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

Do you mean just :%s/;$/, or is the keymapping in your example important for you? — Michael Homer, Aug 14 '18 at 06:51
@Bananguin - that second /is redundant... as is the current actually. :%s/;$ works also. — Lieven Keersmaekers, Aug 14 '18 at 10:08
the mapping wasnt important. :%s/;$ is doing exactly what i want! thx! — divramod, Aug 15 '18 at 04:29

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

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

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

Try the below command using sed,
