Command
以全屏大小顯示自定義文本的應用程序的名稱是什麼？
幾年前我見過一個非常方便的應用程序：命令顯示它的第一個參數被放大以適合整個螢幕。例如…
thiscommand AA…然後您會看到兩個非常大的 A 字母填滿整個螢幕，或者…
thiscommand "name@mail.com"…然後顯示電子郵件地址的寬度等於螢幕的寬度。只需一次擊鍵（可能
q），您就可以關閉它。我認為這個應用程序通常非常有用，當您與人交談或進行展示時，您很快需要顯示一些簡短的文本，只有幾個單詞。我的問題是我忘記了這個程序的名稱，我很努力地通過Google找到，但沒有成功。有人知道嗎？
橫幅；在我的系統上它被稱為
printerbanner. 我打算連結到一個手冊頁，但我找不到一個，無論是線上還是在我的高畫質…
printerbanner橫向列印文本，以允許非常長的字元串，它似乎沒有正常列印的選項。範例（由 slm 提供）

okular. 要使用 ImageMagick / GraphicsMagickdisplay實用程序顯示它：display -geometry 1024x768 -density 72 demo.ps增加密度參數（例如，嘗試 300）以提高渲染圖像的質量。
display您可以使用’-backdrop選項在背景視窗中顯示圖像；使用 Control-Q 關閉視窗。可以修改
(Unix & Linux)demo.ps中的文本字元串；該程序將自動計算要使用的正確字型大小。要將 demo.ps 轉換為 PDF，您可以使用 ImageMagick / GraphicsMagick
convert實用程序convert -page 1024x768 demo.ps demo.pdf但使用起來可能更快（並且輸出更緊湊）
ps2pdfwr -g1024x768 -r72 demo.ps demo.pdf終於，這是我之前談到的 Bash 腳本。不帶 args 或 arg of 執行它以

#!/usr/bin/env bash #Generate a Postscript file that prints a line of text that fills the screen #Written by PM 2Ring 2014.11.01 #Posted to http://unix.stackexchange.com/a/164977/88378 bold(){ echo -e "\x1b[1m$*\x1b[0m"; } help1() { cat << EOF Display a single line of text at the largest scale that fits within the screen (or requested size). This script generates a Postscript program which performs the scaling calculation and sets the text in the requested font. The Postscript file is then displayed using the ImageMagick / GraphicsMagick utility $(bold display), which should be installed on most modern Linux systems. $(bold Usage:) $(basename "$0") [-h] [-bden] [-f fontname] [-g geometry] [-m margin] [-q quality] [-s savename.ps] [-t text] text... Options may be given in any order. $(bold Options:) -h : print this Help & exit. -hh prints extra help. -b : disable the use of a Backdrop window. -d : disable Display of the text. -e : disable backslash Escaping of the text string. -n : use Normal encoding instead of the default ISO Latin1 encoding. -f : the name of the Font, either a PostScript or system font. Default = 'Times-Roman' -g : Geometry, in WIDTHxHEIGHT format. If not given, the current default screen size is used. -m : left & right (&/or top & bottom) Margin (in pixels) around text bounding box. Default = 8 -q : rendering Quality. Default quality = 1.0 -s : Save PostScript. Use $(bold '-s -') to save to stdout. -t : the Text to display. EOF } help2() { cat << EOF By default, $(bold display) shows the text in a backdrop window. You can use Control-Q to close $(bold display) windows, or use a right mouse click to bring up a context menu. See the $(bold display) documentation for further information. $(bold Text) Multiple -t text options may be given, they will be joined together with an intervening space. Any arguments specified after the options will be added to the text, so there is no need to quote the text string, but it will be necessary to use -- to terminate the options section if any of the subsequent text words begin with a - dash. $(bold Font) The font name must conform to the PostScript naming convention, in particular, it cannot contain spaces. So if a font you'd like to use does have spaces in its name try dropping the spaces or replacing them with a - dash. $(bold Quality) The quality setting is essentially an internal scaling factor for the $(bold display) utility. The default quality setting of 1.0 is reasonably fast, but the outline of the text may look jagged, especially with short text strings. Lower quality settings may be a little faster, but the outline can look quite blurry; settings lower than 0.2 are virtually unusable. High quality settings take longer to render but can look quite good; 2.0 should be adequate for most purposes, 4.0 takes quite a while to render but looks great; higher settings take even longer but the improved quality is unlikely to be noticeable. $(bold Save) Normally, the PostScript program generated by this script is simply piped into the $(bold display) utility, but you may save it to a file. This allows you to show (or print) the rendered text with other PostScript utilities. If you wish, you can edit the PostScript program by hand, to change the font, text, page size, etc, as the text scaling calculations are performed within the PostScript program. To display the file "savename.ps" with okular: okular savename.ps To display it with GhostScript in a 1024x768 window: gs -sDEVICE=x11alpha -dBATCH -g1024x768 -r72 savename.ps $(bold Escape) By default, this program prefixes all backslashes $(bold '\\') and parentheses $(bold '()') in the text string with a backslash to convert the string to PostScript form. You can disable this behaviour using the $(bold '-e') option. The PostScript language uses backslash as an escape character, and it uses parentheses instead of quotes to enclose strings; any unmatched parentheses in a string must be backslash escaped (but matched parentheses are ok). PostScript understands various other standard C escape sequences, including character codes represented by backslashed octal sequences, but it does not understand hexadecimal escape sequences. Please see a PostScript reference for further information. $(bold Encoding) By default, this program uses the ISO Latin 1 encoding for text, but you can use PostScript's Normal encoding vector by specifying the $(bold '-n') option. This program does not support Unicode text.
