sudo command not found - making external drive bootable

[Dave_R]

I'm using the following command to make an external drive bootable but getting "command not found".

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

Can anyone see what's wrong?

I've named my device "MyVolume".

Do you have the Install OS X El Capitan (app) in your Applications folder? It can't be a dmg file.

Are you using auto completion (by hitting the Tab key) to get the correct folder and command to execute? I want to make sure that you aren't just copying that command from someplace.

What happens when you type the following command?

which sudo
file [COLOR=#333333]/Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia

[/COLOR]
