cp: copy to readonly file should fail on mac #5257
Description
Found here: nushell/nushell#10097 (comment)
This test should probably fail on mac too (it fails correctly on all other platforms). It is a port from a nushell test.
#[test]
fn dest_no_permissions() {
let ts = TestScenario::new(util_name!());
let at = &ts.fixtures;
at.touch("valid.txt");
at.touch("invalid_perms.txt");
at.set_readonly("invalid_perms.txt");
ts.ucmd()
.args(&["valid.txt", "invalid_perms.txt"])
.fails()
.stderr_contains("invalid_perms.txt")
.stderr_contains("denied");
