I often see tutorials online that connect various commands with different symbols. For example:

command1 |  command2
command1 &  command2
command1 || command2    
command1 && command2

Others seem to be connecting commands to files:

command1  > file1
command1  >> file1

What are these things? What are they called? What do they do? Are there more of them?
