Usually, searching and replacing using sed looks something like this:
sed -e ‘s/abc/yyy/g’ file.txt
Now, how would we for example modify a string of the form:
We can use something like this:
sed -e ‘s/:\/\//::/g;s/\//::/g’ file.txt
But who said that we have to use a slash as a separator when our regular expression is full of slashes?
The following is equivalent but much cleaner:
sed -e ‘s#://#::#g;s#/#::#g’ file.txt
You can use any character as a separator.
