Replace C++ pointer field access symbol to a period, using sed

I'm trying to replace all occurrences of -> with .. I开发者_如何学C've tried the following:

sed -i s/->/./g licensewizard.cpp

But this gives me an error:

sed: -e expression #1, char 3: unterminated `s' command

I'm not sure what's wrong since neither - nor > need to be escaped if I'm not mistaken?

You need to single quote your sed commands so that the shell wont try to interpret any of the chars. In this particular instance, your shell was interpreting the > character to attempt a redirection.

sed -i 's/->/./g' licensewizard.cpp
