Linux more command
On Unix-like operating systems, the more command displays text, one screen at a time.
more is a filter for paging through text one screen at a time. It does not provide as many options or enhancements as less, but is nevertheless quite useful and simple to use.
more [-dlfpcsu] [-num lines] [+/pattern] [+linenum] [file ...]
|-num lines||Sets the number of lines that makes up a screenful. The lines must be an integer.|
|-d||With this option, more prompts the user with the message "[Press space to continue, 'q' to quit.]" and display "[Press 'h' for instructions.]" when an illegal key is pressed, instead of ringing a bell.|
|-l||more usually treats ^L (CONTROL-L, the form feed) as a special character, and pauses after any line containing it. The -l option prevents this behavior.|
|-f||Causes more to count logical, rather than screen lines (i.e., long lines are not wrapped).|
|-p||Do not 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||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 blank line.|
|-u||Do not display underlines.|
|+/string||Search for the string string, and advance to the first line containing string when the file is displayed.|
|+num||Start displaying text at line number num.|
|h, ?||Show help (display a brief command summary). If you forget all the other commands, remember this one!|
|[k]SPACE||Pressing the spacebar displays the next k lines of text. If k is not specified, more displays a full screen of new text.|
|[k]z||Like pressing SPACE, but k becomes the new default number of lines to display.|
|[k]RETURN||Pressing Enter or Return displays next k lines of text. The default is 1 line. If specified, k becomes the new default.|
|[k]d, [k]^D||Pressing d or CONTROL-D scrolls k lines. The default is the current scroll size, which is initially 11 lines. If specified, k becomes the new default.|
|q, Q, ^C||Pressing q, Q, or CONTROL-C (the interrupt key) exits the program.|
|[k]s||Skip forward k lines of text. Defaults to 1.|
|[k]f||Skip forward k screenfuls of text. Defaults to 1.|
|b, ^B||Pressing b or CONTROL-B skips backward k lines of text. Defaults to 1. (This only works when viewing files, not piped input).|
|'||Go to the place where the previous search started.|
|=||Display the current line number.|
|[k]/pattern||Search for the kth occurrence of the regular expression pattern. Defaults to 1.|
|[k]n||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".|
|^L||Pressing CONTROL-L redraws the screen.|
|[k]:n||Go to the kth next file. Defaults to 1.|
|[k]:p||Go to the kth previous file. Defaults to 1.|
|:f||Display the current file name and line number.|
|.||Repeat previous command.|
more uses the values of the following environment variables, if they are defined:
|MORE||Default more options. If this variable is set, more reads as the default set of options to use. Any options specified on the command line override the options specified in $MORE.|
|SHELL||The current shell in use (this variable is normally set by the shell itself at login time).|
|TERM||The current terminal type. This value is used by more to determine the proper way to manipulate the screen.|
