How can I get the output of ls

Question

How can I get the output of ls? I want to add a indirection operator =>, and it's function is same as >, it means in the command line $ls => Files, the list of files in the directory is stored in the file Files

Answer 1

Output redirection (and all other redirection for that matter) is a facility provided by the shell, not by the ls program. The ls just writes its output to standard output and, if the shell has redirected that to a file, that's where it goes.

So, if you want to add a => token, it's the shell that you're going to have to modify, recompile and install. That's not necessarily an easy task, I've made changes to bash in the past and, while it's relatively easy to tinker around the edges (I added an internal command for outputting the PS1 result string), I suspect redirection may be a little more difficult.

Still, it may be a matter of simply creating a new token => and copying the code that's currently executed for >. It may also be that ash, the Minix3 shell, is a lot cleaner than bash. My advice would be to investigate ash, specifically the version found in Minix3, and just have a play.
