How do I replace single quotes with another character in sed?
提问by Srihari
I have a flat file where I have multiple occurrences of strings that contains single quote, e.g. hari'sand leader's.
我有一个平面文件，其中多次出现包含单引号的字符串，例如hari's和leader's。
I want to replace all occurrences of the single quote with space, i.e.
我想用空格替换所有出现的单引号，即
- all occurences of
hari'stohari s - all occurences of
leader'stoleader s
- 出现的所有
hari's来hari s - 出现的所有
leader's来leader s
I tried
我试过
sed -e 's/"'"/ /g' myfile.txt
and
和
sed -e 's/"'"/" "/g' myfile.txt
but they are not giving me the expected result.
但他们没有给我预期的结果。

Try to keep sed commands simple as much as possible. Otherwise you'll get confused of what you'd written reading it later.
尽量保持 sed 命令的简单性。否则你会在以后阅读它时对你写的东西感到困惑。
#!/bin/bash
sed "s/'/ /g" myfile.txt

Just go leave the single quote and put an escaped single quote:
只需离开单引号并放置一个转义的单引号：
sed 's/'\''/ /g' input
also possible with a variable:
也可以使用变量：
quote=\'
sed "s/$quote/ /g" input

This will do what you want to
这将做你想做的事
echo "hari's"| sed 's/\x27/ /g'
It will replace single quotes present anywhere in your file/text. Even if they are used for quoting they will be replaced with spaces. In that case(remove the quotes within a word not at word boundary) you can use the following:
它将替换文件/文本中任何位置的单引号。即使它们用于引用，它们也会被空格替换。在这种情况下（删除不在单词边界的单词内的引号），您可以使用以下内容：
echo "hari's"| sed -re 's/(\<.+)\x27(.+\>)/ /g'

The -i should replace it in the file sed -i 's/“/"/g' filename.txt
-i 应该在文件 sed -i 's/“/”/g' filename.txt 中替换它
if you want backups you can do sed -i.bak 's/“/"/g' filename.txt
如果你想要备份你可以做 sed -i.bak 's/“/”/g' filename.txt
