Updated: 11/06/2021 by Reckoner Promise
On Unix-like operating systems, the more command displays text, one screen at a time.
This page covers the GNU/Linux version of more.
Clarification
more is a filter for paging through text one screen at a time. It does not provide as many options or enhancements every bit less, but is still quite useful and simple to use.
Syntax
more than [-dlfpcsu] [-num lines] [+/pattern] [+linenum] [file ...]
Options
-num lines | Sets the number of lines that makes upwardly a screenful. The lines must be an integer. |
-d | With this option, more prompts the user with the message "[Press space to proceed, 'q' to quit.]" and display "[Press 'h' for instructions.]" when an illegal key is pressed, instead of ringing a bell. |
-fifty | more usually treats ^L (Control-50, the class feed) equally a special graphic symbol, and pauses after whatever line containing it. The -l selection prevents this behavior. |
-f | Causes more than to count logical, rather than screen lines (i.east., long lines are not wrapped). |
-p | Practice non scroll. Instead, clear the whole screen and then display the text. This option is switched on automatically if the more executable is named page. |
-c | Practise not scroll. Instead, pigment each screen from the acme, clearing the remainder of each line equally it is displayed. |
-s | Squeeze multiple bare lines into one bare line. |
-u | Practice not display underlines. |
+/ string | Search for the string cord, and advance to the commencement line containing string when the file is displayed. |
+ num | Starting time displaying text at line number num. |
Commands
When displaying a file, more can be controlled with a set of commands loosely based on the text editor vi. Some commands can be preceded by a decimal number referred to as k in the following descriptions.
h, ? | Show help (display a brief control summary). If you lot forget all the other commands, call back this i! |
[k]Infinite | Pressing the spacebar displays the adjacent yard lines of text. If thou is not specified, more displays a total screen of new text. |
[m]z | Like pressing SPACE, only m becomes the new default number of lines to display. |
[yard]RETURN | Pressing the Enter or Return key displays next yard lines of text. The default is i line. If specified, k becomes the new default. |
[k]d, [k]^D | Pressing d or CONTROL-D scrolls 1000 lines. The default is the electric current roll size, which is initially 11 lines. If specified, thousand becomes the new default. |
q, Q, ^C | Pressing q, Q, or CONTROL-C (the interrupt cardinal) exits the program. |
[k]s | Skip forward one thousand lines of text. Defaults to one. |
[g]f | Skip forward k screenfuls of text. Defaults to ane. |
b, ^B | Pressing b or CONTROL-B skips backward k lines of text. Defaults to 1. (This simply works when viewing files, not piped input). |
' | Get to the place where the previous search started. |
= | Display the current line number. |
[thousand]/ blueprint | Search for the thouth occurrence of the regular expression pattern. Defaults to 1. |
[yard]due north | Search for the kth occurrence of the last regular expression searched for, which defaults to 1. |
! command, :! command | Execute command in a subshell. |
v | Start up an editor at current line. The editor is taken from the environment variable VISUAL if it's defined, or EDITOR if VISUAL is undefined; if neither is defined, defaults to "vi". |

[g]:n | Go to the gth next file. Defaults to i. |
[thousand]:p | Go to the kth previous file. Defaults to i. |
:f | Brandish the current file name and line number. |
. | Echo previous command. |
