Here’s a useful guide for some IT people that are getting into Linux, and more specifically Ubuntu.
Basically, it’s a reference for Windows users to do Linux-type commands. I’ll be adding to this post as time goes on.
sudo -i set the command shell to have root privileges
ifconfig shows network information (ipconfig in Windows)
ifdown eth0 && ifup eth0 restart your network adapter and get new IP address
ifconfig eth0 192.168.99.14 netmask 255.255.255.0 up change your IP address
route add default gw 192.168.99.254 set the default gateway
init 0 shutdown
init 6 reboot
dmesg print diagnostic messages from the kernel
df Show a summary of disk usage
du Show a directory tree space usage (some nice modifiers in this )
tune2fs Allows you to modify disk and filesystem settings. Useful for removing reserved disk space on ext filesystems.
invoke-rc.d service restart Start / Stop a service
update-rc.d service defaults 99 Add service to startup scripts
sudo dpkg-reconfigure flashplugin-installer Reinstall Adobe Flash
uname -a and cat /etc/issue to know what version and distro of Linux you are running
