如何控制 `man -t` PostScript 输出的页面参数（边距、分页）？

我想将几man页打印成几本小册子。我需要调整man -t命令的输出，以便生成的 PostScript 文件将具有分页页码，页面必须在“外”边缘上编号，并且“内”边距必须比“外”宽。我怎样才能实现这个目标？

PS 我所说的“小册子”（“小册子”）编号是指这种编号，因此如果将几页打印的页面一次对折，结果将看起来像一本具有正确顺序页码的书。

朋友前段时间写的一个很棒的shell脚本：livre。

您会对--book和--inner选项感兴趣。

#!/bin/sh
#---------------
# A parametrized replacement for psnup -2 using pstops.
#
# The script computes bounding boxes using gs and deduces optimized reductions
# on two pages per sheet with given margins or scaling. Pages can be arranged
# for various kinds of folding or binding.
#---------------
# Requires: gs, bc, pstops, psbook, pdftops
#---------------

VERSION=2009-12-02

# Output parameters

PAPER=a4
WIDTH=597   # 210mm
HEIGHT=845  # 297mm
MARGIN=30
INNER=1
SCALE=
TWO=false
BIND=top
BBRANGE=-
SIG=
IN=
OUT=
DASHQ=-q
VERBOSE=false
BB_ODD=
BB_EVEN=

usage: livre.sh [options] input output
The input can be in PostScript or PDF, possibly gzipped.
options:
  --margin SIZE    compute scaling to get SIZE-point margins (default: 30)
  --scale FACTOR   use the given scaling FACTOR (overrides --margin)
  --inner FACTOR   set inner margin to FACTOR times the outer one (default: 1)
  --two            input is two-sided
  --top            output should be bound at the top (default)
  --left           output should be bound on the left
  --book           output should be folded into a booklet
  --sig N          select the signature for psbook (implies --book)
  --bbrange PAGES  only use the specified PAGES for bounding box computation
  --bbox BBOX      provide the bounding box explictly, disable its computation
                     (use this twice if the input is two-sided)
  --verbose        do not use quiet mode

这可能不是您问题的完美答案。我所做的是。man -t man > foo.ps。这创建了一个 Postscript 文件。我在Okular（使用 KDE 的默认 PDF/PS 查看器）中打开了它。Okular渲染得foo.ps非常完美，带有页码。现在我可以打印文档了。
