Andreas Kling	e2dbdd14aa	Colorize ls output.	2018-10-28 01:17:48 +02:00
Andreas Kling	8f91a47aeb	Add some basic field width support to printf(). ... Use it to make "ls" output a bit better. Also sys$spawn now fails with EACCES if the path is not a file that's executable by the current uid/gid.	2018-10-27 16:43:03 +02:00
Andreas Kling	9a71c7759a	Implement loading of linked ELF executables. ... This took me a couple hours. :^) The ELF loading code now allocates a single region for the entire file and creates virtual memory mappings for the sections as needed. Very nice!	2018-10-27 14:56:52 +02:00
Andreas Kling	2749e7f1c2	Implement sys$chdir() and teach sh+ls to cd around and browse different dirs.	2018-10-26 14:24:11 +02:00
Andreas Kling	5f36a5f22e	Add an lstat() syscall and use it to make "ls" nicer.	2018-10-24 13:19:36 +02:00
Andreas Kling	bca4b71bfa	Lots of hacking to make a very simple "ls" utility. ... I added a dead-simple malloc that only allows allocations < 4096 bytes. It just forwards the request to mmap() every time. I also added simplified versions of opendir() and readdir().	2018-10-24 12:50:07 +02:00
Andreas Kling	9a296d63f3	Add simplified mmap() and munmap() syscalls.	2018-10-24 09:48:41 +02:00
