I have installed cgminer-3.7.2 from sources. I later wanted to remove the package and followed the instructions provided in install guide. But i am still able to run the program when i type in 'cgminer' in the terminal. How to completely remove the program?
I'm not too familiar with cgminer, but is it possible that it is still running in the background? In that case, a restart might fix things. Also look at /bin/ or /usr/bin/ (when you install a program, a shell script is usually installed here and executed whenever you run the command) and see if there is a file named "cgminer".
If you uninstalled it using its binary, then there shouldn't be any files left except local user config files (which alone would not allow you to run the command).
