install

the simplest way

You can install opy with

$ chmod +x opy
$ sudo cp opy /usr/local/bin/     # Please check PATH.

since opy is an independent script file.

make

The opy file and its manual are copied to /usr/local/bin/ and /usr/local/share/man/man1/ respectively with the following command.

$ sudo make install

homebrew

The version remains old because I don't have a Mac PC anymore...

$ brew tap ryuichiueda/oneliner-python
$ brew install oneliner-python
