One of the primary tricks in my sysadmin bag-o-tricks is Input/Output Redirection; I have found that while many people use Shell I/O Redirection throughout their day not everyone fully understands why and how it works.
The Input and Output In the Unix environment there is always 3 streams open stdin, stdout, & stderr; these special streams are used for interacting with the user input and program output within the Unix/Linux shell environment.
On System V based OS's the /etc/rc.local file is executed by the init process at the end of the systems boot process. The fact that the rc.local file is executed during the boot process makes it an easy target for misuse by lazy Sysadmins. Since I started my Unix experience on FreeBSD which relies primarily on the /etc/rc.* configuration files, I've seen and shamefully contributed to my fair share of misuse in the rc.
As of Solaris 9, Sun introduced a new utility called Service Management Facility. This utility is now (Solaris 11) the preferred method of managing your services. While the /etc/rc.X/ directories are still around and work they are considered legacy.
Here is a quick example of enabling apache to get you started.
# svcs -a | grep http disabled 10:23:11 svc:/network/http:apache22 # svcadm enable http # svcs -a | grep http online 10:30:23 svc:/network/http:apache22 This will enable apache for not only your live session but will also enable it for boot as well.
