How to find what are the configuration files needed for default executables in Linux? Is it possible to find it?
For Example : xhost which has some configuration files.how to find those files by simple way?.
I am not good in OS level.
Most system wide system and software program settings are stored in /etc and sub-directories. User specific settings are generally located in $HOME. You can use the "ls -a" command to show hidden files and directories that start with a period (.). The man page for a command will also typically show where the settings are stored, .e.g. "man xhost". Btw, the xhost program is obsolete and should not be used anymore.
