替换 sed 命令中的奇怪字符

Question 1

Sed 也可以用作脚本（更容易开发）：创建一个文件“nb2txt”

#!/usr/bin/sed -Ef

s/®[^¯]*¯//g
s/-{20,}//g
s/\.{20,}//g

和：

$ chmod 755 nb2txt
$ nb2txt file.nb

$ nb2txt file.nb

Question 2

您的正则表达式使用\|(GNU 中的替代模式sed，大多数其他实现中的文字 bar sed) 和\+(GNU 中的一次或多次出现，大多数其他实现中的sed文字)。如果您使用 GNU ，此模式将删除任何类似或的模式。如果您使用不同的实现，它可能找不到任何匹配项。+sedsed®MD-IT¯®MDDDDDBO¯sed

sed更好地使用扩展正则表达式，多年来大多数版本都支持：

sed -nE 's/®MD-IT¯|®MD+BO¯|®MDNM¯®LL\.8LI,0LI¯|®LL0LI,0LI¯|… and so on

我还建议删除空的替代方案（\|在模式的开始和结束处），尽管它们在这种情况下不会造成损害。

无穷无尽的\.\.\.\.\.\.\.\.\.\.\.\.and----应替换为\.{42}实际-{23}数量的点或破折号。或者可能是通过\-{10,}消除任何出现的 10 个或更多点。

Question 3

从sed -n l列表中可以清楚地看出，您有一个包含许多内容的文件字符 174（十进制或八进制 256）和 [字符 175]（十进制）或 257（八进制）。列为和\256，如果解释为“单字节”字符，\257则可以解释为 Unicode \xae（十六进制代码ae- 或256八进制）或只是，如果解释为单个字符，则可以解释为 Unicode （十六进制代码- 或八进制）或只是字节字符，®\xafaf257¯

$ printf '\256 \257 \n' | iconv -f WINDOWS-1252 -t utf8
® ¯

如果使用 utf8 作为默认编码（Linux 中常用）。

这似乎start和文件end的一些内部编码有关.nb。删除以开头\xae和结尾的字符串\xaf似乎可以让我们更接近您的请求：

$ sed 's/®[^¯]*¯//g' test
Glossary    
A fortiori proposition: If X is true, then how much greater is Y true? To move logically from a stronger argument to establish a weaker argument. The weaker argument is sometimes presented by the speaker as the stronger argument.
Accusative of motion/direction - Indicates movement to the noun marked by the accusative and is to be distinguished from the accusative of local determination which indicates location without motion (Joüon and Muraoka 2006, 428).
Anadiplosis - A figure of speech in which the word that a colon ends with, or a like sounding word, is the word that begins the next colon (Brown, Fitzmyer, Murphy, et al. 1990, 245).
Anaphoric use of the article - When the article is used to indicate that the word to which it is attached is the one previously mentioned (Williams and Beckman 2007, 36). 
Anaptyxis - The insertion of a vowel into a word to avoid a consonant cluster.
Aoristic perfect - I use the phrase 'aoristic perfect' to refer to one of the ways the qatal form can be rendered into English. Aoristic perfect denotes a past situation the implications 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 once. It may have occurred in the recent or distant past but from the standpoint of the speaker it is to be regarded as a fact having occurred and hence as a fact belonging to the past (Joüon and Muraoka 2006, 337; Driver 1998, 12). The term 'aoristic perfect' and indeed the other categorizations of perfect in this grammar, all relate to the interpretation of qatal verbs in their given contexts. The qatal form in and of itself does not convey these meanings. 
Beth essentiae - ÿHá that is used to indicate the predicate of a clause or a word used predicatively (Joüon and Muraoka 2006, 458).
