Let's say I have this command:
/sbin/ifconfig|grep inet|head -1|sed 's/\:/ /'|awk '{print $3}'
Is it possible to shorten this to let's say writing host in the command line?

Yes, you can create shell alias, which is exactly what you need:
$ alias mycmd="/sbin/ifconfig|grep inet|head -1|sed 's/\:/ /'|awk '{print $3}'"
You probably want to have above alias permanent. To achieve this, add the above alias command to the ~/.bashrc file.

$in the awk field i.e.awk '{print \$3}'"to prevent the shell from expanding it during alias creation Oct 30, 2014 at 11:29
~/.bashrcsearch for it on askubuntu should give you plenty of results.
