Linux 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 will prompt 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 will pause after any line that contains it. The -l option will prevent 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.|
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 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 the return key 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 is 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 it as the default set of options to use. Any options specified on the command line will 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.|
