- * BUG: *globbing* isn't performed at all, by any of the utilities
- e.g. ls -R doesn't scan directories with spaces in them
- * ls doesn't skip symlinks. I should add support for that
- * ls -R now works, but uses lots of memory and CPU cycles
- the fix will be to scan directories recursively, but not
- actually do recursion in C. use of a sleep function
- before each new ls() call should fix the CPU cycle issue
- * cat isn't actually cat. in that, it doesn't concatenate files
- ALSO: cat cuts off some text, sha1sums don't match
- when comparing results with other cat implementations
- * start making use of pledge/unveil, but only on openbsd
- * test on lots of unix/unix-like operating systems
- * look at https://github.com/GwenNelson/UnixPatterns
- * nice shell: https://github.com/GwenNelson/face
- NOTE: no license. ask the author to add a compatible license
- * return proper error codes (0 and 1 are incorrect):
- https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html
- * take inspiration maybe from http://heirloom.sourceforge.net/
- * check for possible buffer overflows, especially in head
