    recording stdout to a file

    (Not exactly a programming question.)

    Working in unix interactively, I remember that there was a command that allowed everything that was being written to the screen to also be saved in a file, but I can't remember the name of the command.

    (I don't mean redirecting output of a single command. This was something that, once executed, all subsequent activity on the screen is recorded to a file, until some other key combination ended it.)

    What's the mystery command?

    hah!

    I finally remembered.

    If anyone's interested, the command is "script".

    i dunno, mabey it has something to do with the stdout redirector,
    ls -l > log.log
    I don't know how to make it stay on after the program is finished though.

    when you want to code that program, i suppose its nothing more than opening the STDOUT_FILENO && STDIN_FILENO for reading from it until some special command is received.
    all the data read in can be printed to a file.

    Sorry, been away for a few days.

    Just enter

    script [yourfilename]

    at the command line.

    From that moment on, everything that appears on the terminal screen is also saved to [yourfilename], until you hit control-d to end the script. Now you have a record of everything that appeared on the screen saved to the file that you specified.
