replace old-link-url to new-link-url with sed
提问by Crazy_Bash
I'm writing a script in bash that would replace old-link-url to new-link-url my problem is that sed can't replace the url because of the slashes. If i put just some text it works.
我正在用 bash 编写一个脚本，它将替换 old-link-url 到 new-link-url 我的问题是 sed 由于斜线而无法替换 url。如果我只放一些文字就行了。

我的代码
sed -e s/"$old_link"/"$new_link"/g wget2.html > playlist.txt

sedsupports anycharacter as separator, so if the pattern you are trying to replace contains /, use a different separator. Most commonly used are #and |
sed支持任何字符作为分隔符，因此如果您尝试替换的模式包含/，请使用不同的分隔符。最常用的是#和|
sed 's|foo|bar|g' input
sed 's#foo#bar#g' input

Don't forget to put double quotesif you are using variablesin sedsubstitution. Also, if your variable have /then use a different delimiter for sed. You can use _, %, |, #and many more.
double quotes如果您variables在sed替代中使用，请不要忘记 put 。此外，如果您的变量有/然后使用不同的分隔符sed. 您可以使用_，%，|，#等等。
So may be something like this would work -
所以可能像这样的事情会奏效 -
sed -e "s_"$old_link"_"$new_link"_g" wget2.html > playlist.txt
