1. redirection & quotes expansion ``` bash$ echo "hello" > "file" bash$ ls file bash$ ``` ``` minishell$ echo "hello" > "file" minishell$ ls '"file"' minishell$ ``` 2. redirection & open `prompt$ > newfile` create file `newfile` in bash, but not in minishell 3. redirection & open ok `prompt$ echo "hello" > $not_a_variable` ok does'nt create a file in bash, but does in minishell 4. redirection & variables expansion ``` export NEWVAR="newfile" echo hello > $NEWVAR ``` create file "newfile" in bash, but a file named "'$NEWVAR'" in minishell 5. redireciton & pipes `ls | < not_a_file cat` gives an error about "not_a_file" and stop in bash, but in minishell it continues forever (`< not_a_file cat` works fine in both bash and minishell)
