我在 Fedora Linux 上运行 GNU Ed。GNU Ed 手册隐晦地提到了'r'该命令的后缀s，以区别于'r'命令本身。它只说了以下内容：
后缀
'r'导致re使用最后一次搜索的而不是最后一次替换的 re （如果搜索发生在替换之后）。
我看不出它的用处，尤其是当将 Ed 与 一起使用时rlwrap，使用它可以轻松修改最后的替换。有人可以提供'r'作为后缀的用例吗？
有没有办法让 Ed 创建当前加载到缓冲区的文件的备份。有时我会不小心覆盖我的文件，发现它无法恢复。即制作一个备份文件，在原始文件名后附加一个波浪号（例如，myfile.txt~），其中包含该文件的先前版本。
我想创建一个sed命令，从给定文档中删除所有这些奇怪的字符：
sed -n 's/\|®MD-IT¯\|®MD\+BO¯\|®MDNM¯®LL\.8LI,0LI¯\|®LL0LI,0LI¯\|®MD\+IT¯\|®LL.8LI,0LI¯®MDIT¯\|®MDNM¯®FL¯®LL.8LI,0LI¯\|®FL¯®MD-BO¯\|®FL¯®MD-BO¯\|®MD-BO¯\|¯®OF1IN,1IN¯®FC¯®LL1LI,0LI¯\|\|®SF1,1¯\|®FM1FT=0LI,LR=1;\|®MDSU¯®FN1¯\|®MDNM¯¯\|®IV-RTF\|\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\.\|¯®BF0¯\|®FS1\|-------------------------------------\|¯®FW1\|\|//gp'
这些代码都是在另一个应用程序中创建的Nota Bene，我有很多包含这些代码的文件，我想将它们转换为纯文本，甚至可能是降价。
问题是字符没有被替换。我已经尝试过这样做，Sublime Text并成功地使用 find-replace (regex) 剥离了文档。我最好创建一个sed脚本而不是Sublime用于此任务。
我也尝试过使用Ed，但它也没有找到替代品。

perfect' to refer to one of the ways the qatal form can be rendered i\
nto English. Aoristic perfect denotes a past situation the implicatio\
ns of which are no longer felt in the present. The situation may have\
extended over a period of time and it may have occurred more than on\

1\257\256LL.5LI,0LI\257Classic perfect - I use the phrase 'classic pe\
rfect' to refer to one of the ways the qatal form can be rendered int\
o English. Classic perfect refers to the continuing present relevance\
of a past situation from the perspective of the speaker (Comrie 1976\
, 52). By perfect I do not necessarily imply that a previous situatio\
n has resulted in a state but that the situation has implications rel\
evant to the present. The situation is not merely past and over but s\
omehow persists and continues to intrude into the present. Such verbs\
are usually translated into English using the perfect or present ten\
se. I have included under this definition quasi-stative verbs which r\
efer to attributes which were acquired before, but which are assumed \
to continue in some way up to the present moment (Driver 1998, 11; Jo\
\374on and Muraoka 2006, 333; Waltke and O'Connor 1990, 487). In some\
grammars these are treated separately. However, that creates too man\
y functions for the one perfect form. The term 'classic perfect' and \
indeed the other categorizations of perfect in this grammar all relat\
e to the \256MD+IT\257interpretation \256MD-IT\257of qatal verbs in t\
heir given contexts. The qatal form by itself does not convey these m\
eanings.\r$

do, but what he has already undertaken. \r$
Cohortative of resolve - The cohortative mood normally expresses the \
will of the speaker, but when the speaker has the ability to carry ou\
t what he wants it takes on the coloring of resolve (Van der Merwe et\
al. 1997, 152; Waltke and O'Connor 1990, 573).\r$

我目前在 Windows 上的 Debian WSL 中运行 Gnu ed 1.18 版。如果我编辑具有以下编码的文件：
ASCII text, with CRLF, LF line terminators
或者
ASCII text, with CRLF,
然后 ed 没有正确地将行与j command. 相反，它删除了要连接的第一行。
如果文件是在 ed 中创建的，则不会出现此问题，但它确实会影响在其他程序中创建并随后在 ed 中编辑的文件。在 GNU ed 1.17 中也发现了同样的问题。
这是一个错误吗？如何规避这个问题？
ed如果我通过调用加上任何其他字母为地址添加书签k，我可以稍后通过调用返回到该地址'+letter。我经常制作这些书签，尤其是在浏览长文档时。
g/vim/s//ed/g但是，如果我创建这样一个书签，然后在我尝试返回添加书签的地址时执行全局替换（例如），它就会消失并ed给我Invalid address. 这很奇怪，因为特别是在调用全局替换之后，人们想返回之前所在的位置，因为全局替换重置dot到最后编辑的行。
我在这里错过了什么吗？
仅替换 ed 中第二次/第三次出现的单词/短语的语法是什么？

ls -lt另外按时间排序文件，即最后更改或修改。这是要区分的，
ls -lu它给出了长列表和访问时间，并从 az 对文件进行排序，而不是按最后一次访问。我希望ls -lu按访问时间对文件进行排序，但为此我需要：
ls -lut它以长格式提供列表，打印访问时间，并按访问时间排序。
ERGO，
-t必须表示按时间排序，无论是修改时间还是访问时间，而，
-u表示仅列出访问时间。这并不意味着按访问时间列出和排序。没有任何进一步的论据，-t似乎意味着按修改时间列出并按修改时间排序。以上是否正确。如果没有，我哪里错了？
