-Simple program for finding and reading remote videos with libssh
+Simple shell program for finding and watching remote videos over SFTP.
-
+Use this if you must, but please prefer 9p.
-Inspired by the shell script:
-```bash
-HOST=192.168.1.2
-USER=pi
-PATH=$((ssh $USER@$HOST find /var/www/public/media -type f -name "*mp4" | rev | cut -d'/' -f1 | rev | sort) | dmenu -l 30 | xargs -I% ssh $USER@$HOST find /var/www/public/media -name '"%"')
