x/sys/execabs: Incorrect error reported when executable does not exist #58606
Description
What version of Go are you using (go version)?
Go 1.20, via https://go.dev/play/
Does this issue reproduce with the latest release?
Yes
What operating system and processor architecture are you using (go env)?
What did you do?
package main
import (
"fmt"
"golang.org/x/sys/execabs"
)
func main() {
fmt.Println(execabs.Command("this-command-does-not-exist").Start())
}What did you expect to see?
An error message should complain that the executable was not found in the current PATH, or something along those lines. The os/exec equivalent code returns this error:
exec: "this-command-does-not-exist": executable file not found in $PATH
What did you see instead?
The error reported is:
this-command-does-not-exist resolves to executable in current directory (./this-command-does-not-exist)
(This is not true, there is no such file in the current directory)
