Execute vim substitute command that includes '/' characters

问题

I have a java file in which I wrote /t, instead of \t, the proper notation of the tab escape function. I want to use vim’s substitution feature (:s) but when I do something like this:

:%s//t/\t/g

I get the error message E488: Trailing characters

How can I write the command such that I can execute the substitution? Thank you.

回答1:

Use backslash to escape the characters. So:

:%s/\/t/\\t\g

You can also use a different delimiter like:

:%s@/t@\\t@g

回答2:

Use colons instead of a slash to avoid confusions and errors if what you want to look-up/replace has slashes. This way VIM will be able to parse the sentence correctly.
Then you need to scape the back-slash otherwise VIM will replace /t with tabulations

:%s:/t:\\t:g

Escape the forward slash in your search pattern:

:%s/\/t/\\t/g

or use another separator:

:%s;/t;\\t;g
