使用 shell less 命令的粘性标题

Question

我有一个文本表格，正在使用

less -S -R

显示。

我希望输出的第 3 行和第 4 行（最后 2 条蓝线）成为粘性标题，这样它的工作方式与此处的标题类似。可以用更少的钱做到这一点吗？

在不使用 less 的情况下，它只是一个文本表格（带有表示颜色的特殊字符）。如果您想测试它，可以将此文本复制到

my_file.txt

文件并运行

cat my_file.txt | less -S -R

添加了 

--header 选项，减少了 600 个（于 2022 年 1 月 7 日发布）：

--header=N[,M]
   Sets  the  number  of  header lines and columns displayed on the
   screen.  The value may be of the form "N,M" where N  and  M  are
   integers, to set the header lines to N and the header columns to
   M, or it may be a single integer "N" which sets the header lines
   to  N  and  the  header columns to zero.  When N is nonzero, the
   first N lines at the top of the screen  are  replaced  with  the
   first  N  lines of the file, regardless of what part of the file
   are being viewed.  When M is nonzero, the  characters  displayed
   at  the  beginning  of  each  line are replaced with the first M
   characters of the line, even if the rest of the line is scrolled
   horizontally.   If  either N or M is zero, less stops displaying
   header lines or columns, respectively.  (Note  that  it  may  be
   necessary  to change the setting of the -j option to ensure that
   the target line is not obscured by the header line(s).)
