Eg: cp-r linuxcast.net linuxcast. net2 not only copies the linuxcast.net folder, but also copies all the files in the folder to linuxcast. to display the details of the copy, add-v eg: cp-r-v linuxcast.net linuxcast to the parameter. net3 or cp-rv linuxcast.net linuxcast. net3 will display detailed information. II. move or rename a file or directory 1. use the mv command to move or rename the file or directory format: Target Directory of the mv file. for example: mv linuxcast linuxcast.net/, move the file named "linuxcast" under the current directory to the linuxcast.net folder, this file does not exist in the current directory. Its effect is similar to "cutting ". If you specify a file name, you can rename the file eg: mv linuxcast-2 linuxcast.net/cast1 and move the file named "linuxcast-2" under the current directory to the linuxcast.net folder, and rename the moved file as "cast ". if you do not change the file directory, rename the file mv file name. for example: mv linuxcast liangjin, rename the file named "linuxcast" in the current directory to "liangjjin ". therefore, if you do not specify a directory, directly move it under the current directory to rename it. III. create and delete files 1. you can use the touch command to create an empty file or update the file time. the touch file name is created in the current directory. The touch folder Interactive-r recursively deletes all contents in the directory.-f force deletes, no warning prompt (be careful, impulsive is the devil) format: When the rm file name is deleted from the folder, add the-r parameter format: rm-r folder name eg: rm-r linuxcast.net deletes all the files in linuxcast.net along with the folder without any prompt. This operation is dangerous. important files may be wiped out in an instant. We can add the-I parameter. -I is used to interactively delete files and folders (each time you delete a file system, you will be asked if you are sure to delete it ). For example: rm-ri linuxcast.net/, delete the files in the linuxcast.net folder one by one. you will be asked for comments every time you delete the files. 4. create or delete a directory. use the mkdir command to create a directory. use the rmdir command to delete an empty directory and run the rm-r (-f) command.
