If you change the content of your. bash_profile file, the change will not take effect until you log out and log on again, and the file is read again.

I saw a command line prompt from my colleagues on my system (Linux), which had a color and smiling face. I think it's cool, and I also copied it, Display Policy: current user, time, current directory, If a common user displays a smiling face, the user can operate it at will and follow the $ prompt. If a superuser shows a suface:-| it means to be cautious with the operation and follow the # prompt. Create a ps1.sh file in/etc/profile. d/an

Three-way handshake In TCP, one end that initiates a request is called the "client", and the other end of the passive connection is called the "server 』. Both the client and the server can send and receive data after the TCP connection is established. At first, both the server and client are in the closed status. Before communication starts, both parties must create their respective transmission control blocks (TCB ).After creating a TCB, the server enters the listen status again. At this tim

4.2 Standard Interface Python comes with library files for some standard modules. These library files are described in a separate document (python library file Introduction. Some modules are created in the interpreter. They provide non-verbal core operations that are not included in the interpreter for efficiency, or provide access to the underlying operating system, for example, system call. These modules ge perform different selection Configurations Based on the underlying platform. For exampl

There are many system variables in the Linux system, so where do these variables exist? Why do users automatically have these variables when they log on to the shell? Several configuration files are described below.1,/etc/profile: This file presets a few important variables, such as path, USER, LOGNAME, MAIL, INPUTRC, HOSTNAME, Histsize, Umask, and so on. You can edit the file to add variables to this file, but this is not recommended. If you need to change a variable or add a variable we can cr
