Uninstalling files
 

I'm very new to linux
I have RedHat 7.3
I understood how to unpack, compile and install src files,
but I was wandering, how to uninstall a program ?
I installed Proftpd but I was wishing to uninstall it in order
to install Pureftpd.
Is there some automated procedure to remove all installed files ?
Do I have to do it manually ?
Thanks

if you used an rpm to install
rpm -e proftpd

if you look carefully on many of you INSTALL files you will find out you can type "make clean" to delete some files

ok thanks I will try it :)
