GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.

MORE(1) BSD General Commands Manual MORE(1)NAME
more -- file perusal filter for crt viewing
SYNOPSIS
more [-dlfpcsu] [-num] [+/pattern] [+linenum] [file ...]
DESCRIPTION
More is a filter for paging through text one screenful at a time. This version is especially primitive. Users should realize that less(1)
provides more(1) emulation and extensive enhancements.
OPTIONS
Command line options are described below. Options are also taken from the environment variable MORE (make sure to precede them with a dash
(``-'')) but command line options will override them.
-num This option specifies an integer which is the screen size (in lines).
-d more will prompt the user with the message "[Press space to continue, 'q' to quit.]" and will display "[Press 'h' for instructions.]"
instead of ringing the bell when an illegal key is pressed.
-l more usually treats ^L (form feed) as a special character, and will pause after any line that contains a form feed. The -l option will
prevent this behavior.
-f Causes more to count logical, rather than screen lines (i.e., long lines are not folded).
-p Do not scroll. Instead, clear the whole screen and then display the text.
-c Do not scroll. Instead, paint each screen from the top, clearing the remainder of each line as it is displayed.
-s Squeeze multiple blank lines into one.
-u Suppress underlining.
+/ The +/ option specifies a string that will be searched for before each file is displayed.
+num Start at line number num.
COMMANDS
Interactive commands for more are based on vi(1). Some commands may be preceded by a decimal number, called k in the descriptions below. In
the following descriptions, ^X means control-X.
h or ? Help: display a summary of these commands. If you forget all the other commands, remember this one.
SPACE Display next k lines of text. Defaults to current screen size.
z Display next k lines of text. Defaults to current screen size. Argument becomes new default.
RETURN Display next k lines of text. Defaults to 1. Argument becomes new default.
d or ^D Scroll k lines. Default is current scroll size, initially 11. Argument becomes new default.
q or Q or INTERRUPT
Exit.
s Skip forward k lines of text. Defaults to 1.
f Skip forward k screenfuls of text. Defaults to 1.
b or ^B Skip backwards k screenfuls of text. Defaults to 1. Only works with files, not pipes.
' Go to place where previous search started.
= Display current line number.
/pattern Search for kth occurrence of regular expression. Defaults to 1.
n Search for kth occurrence of last r.e. Defaults to 1.
!<cmd> or :!<cmd>
Execute <cmd> in a subshell
v Start up an editor at current line. The editor is taken from the environment variable VISUAL if defined, or EDITOR if VISUAL is
not defined, or defaults to "vi" if neither VISUAL nor EDITOR is defined.
^L Redraw screen
:n Go to kth next file. Defaults to 1.
:p Go to kth previous file. Defaults to 1.
:f Display current file name and line number
. Repeat previous command
ENVIRONMENT
More utilizes the following environment variables, if they exist:
MORE This variable may be set with favored options to more.
SHELL Current shell in use (normally set by the shell at login time).
TERM Specifies terminal type, used by more to get the terminal characteristics necessary to manipulate the screen.
