- Use `=` instead of `==` for string comparison (POSIX compliance)
- Use `printf '%b'` instead of variable as format string (prevents `%` characters in paths from being interpreted as format specifiers)
- Fix `TRIED_PROFILE` to reference `PROFILE` instead of `NVM_PROFILE` which is known to be empty at that point
