Khaïs COLIN	2ae001e00b	fix(exec/redirections): did not correctly restore fds when executing builtins ...

Khaïs COLIN	cea8043ec9	simple_cmd executing: show error in case execve fails ... We don't have to check the return status, since execve only returns on failure. Fixes #52	2025-04-15 14:41:43 +02:00
