Just a quick update and some questions. I have `realpath` implemented in the `readlink` file. I am using the `readlink` tests as a rough template and working on implementing them and getting them to pass for `realpath`.
http://man7.org/linux/man-pages/man1/realpath.1.html http://man7.org/linux/man-pages/man1/readlink.1.html I saw that options `-v` and `-z` were not implemented for `readlink`. Do we want those options implemented? What about `-z` for `realpath`? I noticed that only the long-form argument `--canonicalize` is turned on. Do you want me to turn on the others? ~Andrew On Sun, Oct 27, 2019 at 6:33 PM Rob Landley <[email protected]> wrote: > > On 10/26/19 1:17 PM, enh wrote: > >> P.S.
