Escape a path for sed search pattern [duplicate]

Answer 1

You need not escape it. Just use other delimiter:

sed "s@<SRC_PATH>@$SRC_PATH@g" template.sh > replaced.sh

But you must be sure that SRC_PATH contains no @ (or other symbol if you choose it).

Answer 2

Use s%$OLDPATH%$NEWPATH%. You can choose your delimiter. If % is too dangerous, consider Control-A instead.
