Setting fully qualified domain name for Apache server

Edit /etc/apache2/httpd.conf

Search, using ctrl-w, for ServerName

Uncomment this line:

#ServerName www.example.com:80

and then change the last part to “localhost”

ServerName localhost

 

Stopped jobs in linux

When using CTRL-Z to “exit” a program, you really are not exiting it. You are suspending it. (Multitasking, remember?)

To see the list of stopped jobs, type jobs

To bring the last stopped job up again, and resume its execution, type fg

You can also get the job number from the jobs  listing, and put it after fg like this: fg 1

Some programs can be quit with CTRL-C, while others have a specific key, like Q that must be pressed.
