Shell replace forward slashes with backslashes

Question

I have a question: how to replace forward slashes with backslashes?

I have string:

App/Models

And I need

App\Models

Thank you very much

Where do you have this string? In a file or in a variable? Is it part of some larger piece of data that also has slashes that should _not_ be changed? What shell are you using? — Kusalananda, May 27 '20 at 15:41

Try this (in e.g. bash),

string="App/Models"
echo "${string//\//\\}"

or if you don't have it as variable, you can use tr:

printf '%s\n' "App/Models" | tr '/' '\'

It's a bit tough to parse out what's happening here among the mess of '\' and '/', it would be helpful to break down the pieces of the substitution, or point to some documentation where we could read about substitutions (I'm finding it a bit hard to find such documentation) – MichaelChirico Mar 16 '23 at 00:35

$ printf '%s\n' "App/Models" | sed -e 's|/|\\|g'
App\Models

Use `y///` rather than `s///g` to change single characters globally in `sed`, it's much more efficient. In this case, the `tr` utility would have been a better fit though. – Kusalananda May 27 '20 at 19:02
