Is it possible to shorten a unix terminal command to a shorter one?

Question

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?

Answer 1

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.
