Having to escape forwardslashes when using sed can be a pain. However, it's possible to instead of using / as the separator to use : .
I found this by trying to substitute $PWD into my pattern, like so
sed "s/~.*/$PWD/" file.txt
Of course, $PWD will expand to a character string that begins with a / , which will make sed spit out an error such as "sed: -e expression #1, char 8: unknown option to `s'".
So simply changing it to
sed "s:~.*:$PWD:" file.txt
did the trick.
