7-zip wont open through the command line
 

I have the latest ubuntu distro, and 7 zip. But the current archiver is driving me crazy, I'm trying to unrar 3cd's but it will only find one cd. I go to the terminal and type out 7 zip , 7-zip, 7zip, and it keeps telling me wrong command or there is no command. Any ideas ? And if this has alrdy been posted and I haven't found it in search im sorry mods :study:

did you try to chmod to 777?

can you list the directory contents of the file you are trying to execute for us?
