Bash command questions
1 - I want to do a ls command, but that directs explicity to a file and to the standard output at the same time. How should i do?
2 - What means the command "ls 2>&1"? What means "2>" and "&1"?
3 - As as user, when I do a find command, sometimes appears that the find can search in a specified directory because it's belongs to root and I don't have permission. How can I make disappear this error messages, during the execution of the command?
