VPS Novice Tutorial: Common Linux Commands

1. The tar command is mainly used for packaging and decompression

 #Tar cvf a.tar.gz/home #Tar xvf a.tar.gz (unzip a.tar.gz to the current folder, or zxvf) tar czvf Tar czvf/root/x.tar.gz/home/y/Note: directly package the/home/y/directory and name it x.tar.gz and store it in the/root/x directory. tar xzvf Tar xzvf/root/x.tar.gz/home/y/Note: Extract x.tar.gz from the/root/directory to the/home/y/directory.

2. The mv command is used to move files and folders

 #Mv a.tar.gz/home (move a.tar.gz under the current directory to the home directory) #Mv a.tar.gz b.tar.gz (renamed a.tar.gz to b.tar.gz) Mv/root/x.tar.gz/home/y/Note: Move x.tar.gz from the/root/directory to the/home/y/directory.

3. The rm command deletes files and folders

 #Rm a.tar.gz (delete a.tar.gz, then confirm and enter y) #Rm – r (Confirm the deletion of directories one by one) #Rm – rf (forced deletion, unconfirmed) Rm - rf/root/x.tar.gz Description: Delete the x.tar.gz file in the root directory Rm - rf/root/z/Note: If you delete the z folder of root, all files in the Z folder will be deleted

4. The cd command changes the current directory

 #Cd/home/wwwroot (enter the/home/wwwroot directory) #cd ..  (Enter the upper level directory) #Cd – (enter the last directory) #Cd/(enter the root directory)
