# dotfiles
features: i3, neovim
# how to install on new computer
```sh
# to enable internet using networkmanager (because KDE gui is buggy)
nmtui
# OR to enable internet using wpa_supplicant
ip address show # to show , e.g. wlp3s0
iwlist scanning # to show SSID of network you want to connect to
wpa_passphrase > /tmp/wifi.conf
wpa_supplicant -Dwext -i -C/tmp/wifi.conf

zpool import mypool # to import alredy created pool (searches all /dev/*)
zfs list # to list filesystems
zpool list # to list pools
zpool status # to show pool status
zdb # to show type of each disk in pool
