I often want to read output from the terminal from the beginning but by default I have to scroll back up. This can be laborious when there is a lot of text. Is there anything I can do about this?

Thanks :)

    Pipe it through less. Example:
    dmesg | less

    The pipe character basically takes the output (STDOUT to be specific) of one command and provides it as input (STDIN) to the next command. It’s one of the many ways of redirecting in linux.

    Some relevant examples:
    dmesg > dmesg.txt …(over)writes the ouput to a file
    dmesg >> dmesg.txt …appends the output to a file
    ps aux | grep bash …pipe, as described above. The tidbit is that grep only prints lines matching the pattern specified
    find / -name somefilename 2>&1 >result.txt …redirects warnings and errors (STDERR) to STDOUT, so that you don’t have to treat those separately.
