I have the following command cat urls.txt | sed 's/com/com\//' which will add a slash in the last of url but the problem is whenever if there are other tlds like net and org it won't work, how I can make it to add the slash without specifying the tld

Tried to add a slash in url without to without specifying the tld

CodePudding user response：

$ means "end of line" in sed regexes. Therefore,

sed 's=$=/='

will add a slash to each line's end.

Note that it uses a different delimiter than / to prevent the need of a backslash which improves readability.
