Step s201: add the row that a line starts finger daemon with absolute path using the end in/etc/rc.local
Mode Linux system start after start finger daemon.
Finger daemon is formed with shell Scripting Edition, shell script, that is, under shell script, with windows/dos
Batch processing similar, that is, be placed in advance in in a file with all kinds of orders, a program literary composition of convenient disposable execution
Part, mainly facilitates the manager to be configured or manages.But it is more powerful than the batch processing under windows, than with
The program efficiency of other programs editor is higher, and it employs the order under linux/unix after all.Also it is said differently
It is that shell script is the program write using the function of shell, and this program is to use text-only file, by some
The grammer of shell and instruction write on the inside, the function such as then use normal representation method, pipeline order and data flow to be redirected, with
Reach the processing intent that we are wanted.For more expressly, shell script is just as the .bat in age early stage dos, simplest
Function is exactly write whole for many instruction remittances together, allows user easily just an operation can execute multiple orders, and
Shell script more there is provided array, circulation, the critical function such as condition and logical judgment, allow user can directly with
Shell, to write a program, is similar to, without using, the grammer that the traditional programs such as c program language are write.
Start finger daemon, we can add a line with exhausted at the end of/etc/rc.local after Linux system start
To path start script (i.e. the row of finger daemon a) because Linux system Starting mode and execution order are:
A, loading kernel；
B, execution init program；
First script that c ,/etc/rc.d/rc.sysinit# are executed by init；
D ,/etc/rc.d/rc $ runlevel# $ runlevel are default operational mode；
After e ,/etc/rc.d/rc.local# appropriate level service start, execute this document again, in fact can also be need
Order to be executed is write in this document, such as our finger daemon a；
F ,/sbin/mingetty# wait User logs in.
