How to handle unix paths (\) with node?

Question

I have an array like this:

var array = ['File Name', ...]

I'm executing unix commands like this:

for (const item of array) {
   execSync(`convert -trim ./original/${item}.png ./trimmed/${item}.png`)
}

Here I get an error because unix format spaces like this File\ Name. So, in my code, the script can't file the original file.

What is the usual way to handle this?

You can surround the name with quotes. It's the usual way to handle spaces in the path. — VLAZ

execSync(`convert -trim "./original/${item}.png" "./trimmed/${item}.png"`) — VLAZ

To avoid problems with spaces, you can simply surround the full path in double quotes. It's a very common way for the shell to handle spaces in paths:

execSync(`convert -trim "./original/${item}.png" "./trimmed/${item}.png"`)

The other way of handling spaces is to escape them but it gets ugly as you also need to escape the escapes, if you don't need a space. It also makes reading the path really hard when debugging and overall it's probably not worth the hassle.
