For example, vim cannot run (running) in the background! He won't run because you didn't input the data! In addition, you cannot use [ctrl] + c to terminate the work in the background 』! In short, the following restrictions must be noted for bash job control: The program triggered by these jobs must come from your shell subroutine (o

that when a job that is put into the background wants to run, he must not be able to interact with the user. For example, VIM is absolutely impossible to run in the background (running)! Because you didn't enter the data, he wouldn't run! and the job of putting the background is not to use [ctrl]+c to terminate!] In summary, the restrictions that you must notice to perform the job control for bash are: The programs triggered by these jobs must come from your shell's subroutines (just m

RAID5 is installed with RAID0. This provides both read and write capabilities and data redundancy. Fault Tolerance function: provide redundancy function disk utilization :( N-2)/n disk capacity: N-2 5, RAID in linux system implementation: 1, RAID implementation has two ways: hard RAID and soft RAID. Hard RAID is the assumption of RAID Arrays on hardware, requiring hosts to have RAID cards and RAID controllers. Then, set it in the BIOS of the computer. We will not detail it here. Soft RAID: Prov

First, this semester began to learn python, but looked at Python2 and Python3, and finally chose the Python3In the spirit of familiarity with Python, and also want to do some small programs to increase their proficiency in python. So write a simple program, this small program to achieve the BASA64, base32 the addition of decoding. And added a MD5-generated feature. PS: I think Python development is also very fun ...Second, run the program:The above is the overall interface of the program.Third,
