Hey Tony, to get it to work, instead of an alias do this in the Terminal (newline = enter & assumes you know vim/nano):

sudo touch /usr/local/sbin/mem
sudo [vim or nano] /usr/local/sbin/mem

Then put this in:

#!/bin/sh
top -l 1 | awk ‘/PhysMem/ {print “Used: ” $8 “\nFree: ” $10}’

And save & exit. Now do:

sudo chmod +x /usr/local/sbin/mem

Done! Now you can test with with just typing “men” and you’ll get something like this:

Used: 2805M
Free: 5380M

Enjoy!

Hi, Is there a terminal command that can stop Software Update from deleting the packages once they are installed… I want to save them so that I only download them once, to save them for a OS reinstall/backup and to install on another computer.

AND @Eldon, if you reset the factory default settings on your printer, it might suddenly become obvious to your mac… (from experience).

This would be a great place to show a command that would provide an IP address for a printer or other peripheral. I’ve spent a week trying to add a printer – and I know the printer works.

What would I get if I typed ipconfig in the Terminal?

Happy New Year!

Hi,

I’m trying to run this command as an alias in my .bashrc file

alias mem=”top -l 1 | awk ‘/PhysMem/ {print “Used: ” $8 ” Free: ” $10}’”

it works fine as a standalone command in terminal but not as alias. Any help is appreciated. Thanks.

no, only if you were to change your network card

Does my mac adresse change if I upgrade my computer with some other hardware? For example change the graphic card?
