sed稀有分隔符（& | / /？...除外） [英] sed rare-delimiter (other than & | / ?...)

问题描述

我必须在字符串上应用Unix命令 sed （可以包含＃，！，/，？，&，@和所有其他字符），可以包含所有类型的字符（&，|，！，/ 、? ...）

I've to apply the Unix command sed on a string (can contain #, !, /, ?, &, @ and all other characters) which can contains all types of character (&, |, !, /, ? ...)

它是一个复杂的定界符（带有两个caracter吗？），可以允许克服错误：

Is it a complex delimiter (with two caracters ?) which can permits to outpass the error :

sed: -e expression #1, char 22: unknown option to `s'

预先感谢

推荐答案

sed中的多字符表达式定界符没有这样的选项，但是我怀疑
是否需要它。分隔符不应出现在 pattern 中，但如果它出现在正在处理的字符串中，则不会有问题。而且，除非您做的事情非常怪异，否则搜索模式中总会出现一些字符，可以用作分隔符。

There is no such option for multi-character expression delimiters in sed, but I doubt you need that. The delimiter character should not occur in the pattern, but if it appears in the string being processed, it's not a problem. And unless you're doing something extremely weird, there will always be some character that doesn't appear in your search pattern that can serve as a delimiter.
