Need help with a terminal command

[Seadevil]

I found a Brother printer driver installer & the instructions said to enter the following command in terminal:

Su Command: gunzip linux-br-printer-installer-1.0.0-1.gz

I entered this in the dir with the installer file. But I

get "UNKOWN ID: Command

I made command all lowercase, tried without the colon, but

same error message.

what is wrong with the command ?

I don't think the 'Su command:' part is meant to be taken literally - just


gunzip linux-br-printer-installer-1.0.0-1.gzThere should be no need to use elevated permissions unless you are unzipping directly in a system directory - if you are, then the correct way in Ubuntu would use 'sudo' not 'su' anyway


sudo gunzip linux-br-printer-installer-1.0.0-1.gz

The su is to switch you to the sudo (administrator) command. So in a terminal cd to the directory with the driver and enter su. This will prompt you to enter your password. Then run the rest of the install, type in gunzip linux-br-printer-installer-1.0.0-1.gz

thank you all VERY much. If he put Command: in parentheses, i would have understood that was NOT part of the command. lol.
