It's not clear what you're asking here. Do you want to type "l s &" (no RET) and have a directory listing show up? While you might be able to configure your shell to do this, it prevents you from typing anything else on the line. My shell (zsh) supports a "&!" modifier at the end of the line, as well as just "&", and this would be impossible with this setup. It also prevents you from typing more commands (i.e. "make &; ls &"). Sometimes, though, things happen in a non-intuitive way. You type "l s & RET", and see a directory listing with no shell prompt. There actually _is_ a shell prompt, and if you type "ls" again without pressing RET first, you'll get another directory listing. What happens: -- You type "ls &". -- Shell starts another process to do the directory listing. -- Shell prints its next prompt and starts waiting for input. -- ls starts up and prints a directory listing. Pressing RET here causes the shell to say to itself, "oh, we just got an empty line, let's display another prompt." The ls process is actually finished here.
