Redirections, Pipes and Signals
Managing streams

These are the redirectors that we can use to take control of the streams of our programs

    command > file: redirects standard output, overwrites file
    command >> file: redirects standard output, appends to file
    command < file: redirects standard input from file
    command 2> file: redirects standard error to file
    command1 | command2: connects the output of command1 to the input of command2
