Operating Systems OS X (Apple) How to execute a command when system boots? Post 302511472 by andrewust on Wednesday 6th of April 2011 11:08:40 PM

I am the only user of this machine. So I guess I will choose (1).
Could you give me an example? I would like to create a ram disk when system starts up, so that I can use it as a temp folder. The command is:
diskutil erasevolume HFS+ 'ramdisk' `hdiutil attach -nomount ram://262144`

Thanks!
