linux - Shell scripting practicing environment. -

i want learn linux , shell scripting out installing linux on machine. used linuzoo.com site provides environment practicing machine not open terminal.

i'm not entirely sure question - asking (1) how practice or (2) why linuzoo.com giving problems?

regardless, i'd recommend using virtual machine, instead of kind of simulator or phony shell. there's no substitute real linux environment. virtualbox extremely powerful, free, , open-source virtualization environment, i'd start there.
