Retty is a tool for changing stdin,stdout,stderr of a running process (http://pasky.or.cz/dev/retty/) which may be handy if you want to attach to a process running e.g. from a died ssh session, changing running process to run from under screen(1) etc.. Currently it doesn't work for 64-bit systems and it doesn't handle changing of a controlling tty of a process (which may be possible using setsid() and opening a new tty). The aim of this project it to fix the above deficiencies and package the tool in OBS.
This project is one of its kind!
