When you say

file ="$1"

with a space after "file", you're running something called file with =$1 as an argument. There probably actually is a utility called file. If you want to assign $1 to a variable called file, you don't need the space:

file="$1"

    No "probably" about it; `file` is a [standard utility](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/file.html). – chepner Sep 11 '20 at 19:21
  • It's reasonable to assume that _that_ `file` is the one being invoked here, but it's an assumption. Container-based Linux images may not include `file` or, in fact, any of the 'standard' utilities. – Kevin Boone Sep 13 '20 at 06:44

there shouldn't be a space before = in the second line. file=$1 should be good enough.

Check what shellcheck says about your code:

 ^-- SC1068: Don't put spaces around the = in assignments (or
 quote to make it literal).

You can read more about SC1068 case on its Github page.

#!/bin/bash

file=$1

code $file

echo "aberto o arquivo ${file} no vscode"

I made this code snippet to demonstrate, I pass a path and it opens the file in vscode
