You can also do it with all single quotes:
您也可以使用所有单引号进行操作：
echo "Hel'lo" | sed 's/'\''/\'\''/g'
And since your question is also tagged bash, I might as well point out that you don't even need sed:
而且由于您的问题也被标记为bash，我不妨指出您甚至不需要 sed：
[ghoti@pc ~]$ foo="Hel'lo"
[ghoti@pc ~]$ echo "${foo/\'/\'}"
Hel\'lo
回答by Adrian Pronk
Or without quoting the sed argument:
或者不引用 sed 参数：
echo "Hel'lo" | sed s/\'/\\\'/g

这可能对你有用：
echo "Hel'lo" | sed 's/'\''/\&/'
