Andreas Kling	ec1d16b307	Add a "pwd" utility to userland. ... It's implemented as a separate process. How cute is that. Tasks now have a current working directory. Spawned tasks inherit their parent task's working directory. Currently everyone just uses "/" as there's no way to chdir().	2018-10-24 14:28:22 +02:00

Andreas Kling	ed2422d7af	Start adding a basic /proc filesystem and a "ps" utility.	2018-10-23 12:04:03 +02:00
Andreas Kling	fe237ee215	Lots of hacking: ... - Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard. - Implement MM::unmapRegionsForTask() and MM::unmapRegion() - Save SS correctly on interrupt. - Add a simple Spawn syscall for launching another process. - Move a bunch of IO syscall debug output behind DEBUG_IO. - Have ASSERT do a "cli" immediately when failing. This makes the output look proper every time. - Implement a bunch of syscalls in LibC. - Add a simple shell ("sh"). All it can do now is read a line of text from /dev/keyboard and then try launching the specified executable by calling spawn(). There are definitely bugs in here, but we're moving on forward.	2018-10-23 10:12:50 +02:00
