When the CLI displays output, it sends data through a simple more-like process. This prevents data from scrolling off the screen before you view it. After you see the MORE prompt, press Enter to see the next screen of data. If you type q (followed by pressing the Enter key), the CLI discards any data it hasn’t yet displayed.
You can control the number of lines displayed between prompts by using the dset command to set the LINES_PER_SCREEN CLI variable. (For more information, see the TotalView for HPC Reference Guide.)
