ls -l

An implementation of the LS(1) done for a job interview in about 8 hours. Only supports the -l option. The intent was to resemble the functionality and output of /usr/bin/ls as closely as reasonably possible.

Example

$ ./ls -l src/
total 48
-rw-rw-r-- 1 user user   871 Dec  5  2020 list.c 
-rw-rw-r-- 1 user user  1176 Dec  5  2020 list.h 
-rw-rw-r-- 1 user user 14372 Dec  5  2020 main.c
