Translate characters in vim like with tr

Question

I want to translate characters in vim like with the command line tool tr or with sed:

$ echo 'foo bar' | sed 'y/for/tes/'
tee bas

So I want to replace all occurrences of certain characters with other characters.

Answer 1

You can filter the content of the buffer through arbitrary external commands with :help :range! so you can simply use the tools you are used to:

:%!sed 'y/for/tes/'
:%!tr for tes
