Certain block-mode terminals do not have all the capabilities necessary to support the complete more definition; they are incapable of accepting commands that are not terminated with a . Implementations that support such terminals shall provide an operating mode to more in which all commands can be terminated with a on those terminals. This mode: Shall not affect users on the capable terminals from using more as described in this volume of POSIX.1-2017 If a screen is to be written that has no lines in common with the current screen, or more is writing its first screen, more shall not scroll the screen, but instead shall redraw each line of the screen in turn, from the top of the screen to the bottom. In addition, if more is writing its first screen, the screen shall be cleared. This option may be silently ignored on devices with insufficient terminal capabilities. Exit immediately after writing the last line of the last file in the argument list; see the EXTENDED DESCRIPTION section. Specify the number of lines per screenful. The number argument is a positive decimal integer. The -n option shall override any values obtained from any other source. If the tag specifies a line number, the first line of the display shall contain the beginning of that line. If the tag specifies a pattern, the first line of the display shall contain the beginning of the matching text from the first line of the file that contains that pattern. If the line does not exist in the file or matching text is not found, an informational message to this effect shall be displayed, and more shall display the default screen as if -t had not been specified. The input files being examined shall be text files. If standard output is a terminal, standard error shall be used to read commands from the user. If standard output is a terminal, standard error is not readable, and command input is needed, more may attempt to obtain user commands from the controlling terminal (for example, /dev/tty ); otherwise, more shall terminate with an error indicating that it was unable to read user commands. If standard output is not a terminal, no error shall result if standard error cannot be opened for reading. Override the system-selected horizontal display line size. See XBD Environment Variables for valid values and results when it is unset or null. Provide a default value for the internationalization variables that are unset or null. (See XBD Internationalization Variables for the precedence of internationalization variables used to determine the values of locale categories.) If set to a non-empty string value, override the values of all the other internationalization variables. Determine the locale for the behavior of ranges, equivalence classes, and multi-character collating elements within regular expressions. Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multi-byte characters in arguments and input files) and the behavior of character classes within regular expressions. Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error and informative messages written to standard output. [XSI) ] ![[Option Start]]( Determine the location of message catalogs for the processing of LC MESSAGES. ![[Option End]]( Override the system-selected vertical screen size, used as the number of lines in a screenful. See XBD Environment Variables for valid values and results when it is unset or null. The -n option shall take precedence over the LINES variable for determining the number of lines in a screenful. Determine a string containing options described in the OPTIONS section preceded with characters and -separated as on the command line. Any command line options shall be processed after those in the MORE variable, as if the command line were: The MORE variable shall take precedence over the TERM and LINES variables for determini
