Common commands for Linux VPS novices

For novices only, veterans please don’t read this!
With these commands, there is basically no problem using a VPS, that's what I do :)

【cd】
The cd command not only displays the current status, but also changes the current status. The cd in Linux is similar to that in DOS.
#cd /home/wwwroot (enter the /home/wwwroot directory)
#cd .. (enter the previous directory)
#cd – (Enter the last directory entered)
#cd / (enter the root directory)
【tar】
The tar command is commonly used in the packaging, backup and decompression process in VPS.
#tar cvf a.tar.gz *.* (Pack all files in the current directory and compress them into a.tar.gz file)
#tar cvf a.tar.gz /home (pack all files in the home folder and compress them into the file name a.tar.gz)
#tar xvf a.tar.gz (decompress a.tar.gz to the current folder, you can also use zxvf)
#tar tvf a.tar.gz (browse the files in the a.tar.gz compressed package)
【rm】
rm is the delete command in Linux.
#rm a.tar.gz (delete a.tar.gz, then a confirmation message will appear, enter y)
#rm –r (delete directories one by one and confirm)
#rm –rf (forced deletion, no confirmation)
【ls】
ls is equivalent to dir in DOS command, which lists the files in the current directory. (Note: dir can also be used in Linux)
#ls (list directory files)
#ls –l (list files and display detailed information)
#ls -l |more (too many directories to display on split screen)
【mv】
mv is the same as move, but it also has the function of renaming.
#mv a.tar.gz /home (move a.tar.gz in the current directory to the home directory)
#mv a.tar.gz b.tar.gz (rename a.tar.gz to b.tar.gz)
【cp】
The full name of cp is copy, which naturally means copy.
#cp a.tar.g /home (Copy a.tar.gz in the directory to the home directory. You can select multiple files at a time. Just add the file name after cp)
#cp –R (copy the entire directory, including subdirectories)
Other commands
#mkdir (create directory)
#su (Switch User)
#pwd (display the user's current directory)
#wget (download from source file)
#ftp (Connect to FTP)
#passwd (Change password)
#reboot (reboot)
