binary not in PATH variable - how to execute it?

Question

There is a binary in my home directory: "foo"
My PATH variable doesn't contains my home dir.
I cannot change my PATH varible, since it's read-only

Question: How can I execute this binary without using the following:

./foo
. ./foo

Answer 1

Try this:

create a parse.sh file with content:

#!/bin/bash
export PATH=$PATH:./
foo

execute with bash --noprofile --norc parse.sh
