[SOLVED] sed: -i may not be used with stdin on Mac OS X

Issue

I am using a bison parser in my project. When I run the following command:

sed -i y.tab.c -e "s/  __attribute__ ((__unused__))$/# ifndef __cplusplus\n  __attribute__ ((__unused__));\n# endif/"

I get this error sed: -i may not be used with stdin

The command works fine in linux machines. I am using Mac OS X 10.9. It throws an error only on mac os x. I am not sure why. Can anyone help?

Thanks

Solution

You need to put the input file as the last parameter.

sed -i -e "s/  __attribute__ ((__unused__))$/# ifndef __cplusplus\n  __attribute__ ((__unused__));\n# endif/" y.tab.c
