There is a "more" command that comes with util-linux, but it will not work for this project. The reason is because of library dependencies and space constraints. The util-linux supplied "more" needs either the libncurses or libtermcap to work and there just is not enough space on the root disk floppy to fit everything in. So, in order to have a "more" command we will have to get creative.
The "more" command is used to display a file page-by-page. It's a little like having a "cat" command that pauses every twenty-five lines. The basic logic is outlined below.
Read one line of the file.
Display the line on the screen.
If 25 lines have been displayed, pause.
Loop and do it again.
Of course there are some details left out like what to do if the screen dimensions are not what we anticipated, but overall it is a fair representation of what "more" does. Given this simple program logic, it should not be hard to put together a short shell script that emulates the basic functionality of "more". The BASH(1) manpage and Adv-BASH-Scripting-Guide will serve as references.
The "more" script will need access to device files that are not on the root disk yet. Specifically "more" needs to have stdin, stdout and stderr, but while we are at it we should check for any other missing /dev files. The Linux Standard Base requires null, zero and tty to be present in the /dev directory. Files for null and tty already exist from previous phases of the project, but we still need /dev/zero. We can refer to "devices.txt" in the Linux source code "Documentation" directory for major and minor numbers.
These three packages can be found by using some of the same Internet resources we have used before. The procps package shows up in an Ibiblio LSM search (http://www.ibiblio.org/pub/linux/) for the keyword "ps". The "sed" and "ed" packages can be found on the GNU ftp server at ftp://ftp.gnu.org.
Both "sed" and "ed" packages feature GNU's familiar ./configure script and are therefore very easy to build. There is no ./configure script for "procps" but this does not make things too difficult. We can just read the package's "INSTALL" file to find out about how to set various configuration options. We can use one of these options to avoid the complexity of using and installing libproc. Setting SHARED=0 makes "libproc" an integrated part of "ps" rather than a separate, shared library.
