Debian

Notes for Debian 10 Buster

`command not found`

Commands in /sbin (/usr/sbin) like shutdown, reboot, usermod, useradd not found, even after su.

Use full path to (root) commands: /sbin/reboot

Or, explicitly tell the su to set environment variable with the switch -, like su -

Run script as another user:

#/bin/su -s /usr/bin/php -c "thescript.php" "www-data"

List interfaces: ls /sys/class/net/

Interfaces seems to be configured in /etc/network/interfaces rather than /etc/dhcpcd.conf
