When we write a script under Windows, after the submission to the server, after the update, when you run the time you will see that the file does not exist, but that the file does exist, that is what the reason, is actually the format of the file caused, because we in the Windows After writing, we update to the Linux writing when her format or dos so we want to convert this DOS format to the same format as the System UNIX format:1, when we use VIM to
A Brief Study of some basic command line text editing programs that can save time and effort. Text editing is usually performed interactively in the text editor application. However, some tasks can be conveniently and quickly completed directly from the UNIX command line. In addition, you can use these single-command-line programs in the script to automate various editing processes.Most

Operating systemThe interface between user and computer hardware is to control and manage various hardware and software resources in the computer. It is a multi-user, multi-tasking, time-sharing operating system.For CTSS: If a process requires 16 time slices, it is now assigned only 10 according to priority and is ready to go.

Initially, the target file is called the intermediate representation of the code because it acts as input to the connection editor (that is, the connector), and the connection editor eventually completes the entire task and generates the executable program as output.

This editor is the most commonly used tool in all computer systems. In UNIX, the editors include ex, sed, and VI. Among them, VI is the most widely used, while VI commands are numerous.

Shell scripts are compatible with linux/unix and windows/cygwin, and are set on notepad: edit-> archive format conversion-> convert to UNIX format.

Many programming friends of Chen Hao asked me a few questions online. how do I learn Unix? How is Unix so difficult? How can we learn well? And let me give them some experience in learning Unix. Most of the time, I found that friends who asked these questions have two characteristics: 1) fear of Unix and lack of confid
The Unix tradition tends to delegate a task to a process, but within a task is not just a thread, like all members of a company, everyone is doing the same thing, everyone is only part of it, and when the grain size is reduced, everything can be done at the same time, anyway, Everyone also shares all the resources. So there is a thread. Threads are a different thread of shared resources. The semantics of threading are different from plain

The crontab command is common in UNIX and unix-based operating systems, and is used to set periodically executed instructions. This command reads the instruction from the standard input device and stores it in a "crontab" file for later reading and execution.
Typically, crontab stored instructions are activated by the daemon, Crond often run in the background, checking every minute for
