Common tools for file management in Linux

Common Tools for file management: CP, MV and RM
Copy command: CP (copy)
Use format:

                            cp [OPTION]... [-T] SOURCE DEST                            cp [OPTION]... SOURCE... DIRECTORY                            cp [OPTION]... -t DIRECTORY SOURCE...    简述            1、当SOURCE是一个文件时                    如果DEST不存在时，则新建文件，并把SOURCE中的内容填充到新

File, when dest exists and is a file, the file is overwritten if dest is an eye-

folder, the file is placed in the directory.

           2 、当SOURCE是多个文件时                     如果DEST不存在，则报错，当DEST存在且为一个文件时也报错，当

When Dest is a directory, all the files in the source are placed in that directory.

         3、当SOURCE是一个目录时，要配合－r选项                    当DEST不存在时，则创建指定名称的目录，并将SOURCE中的所有文

Copy to the newly created specified directory. When Dest exists and is a file, an error occurs. When

When a dest exists and is a directory, the contents of two directories are merged, and if there is a file with the same name, the

Files in the source directory overwrite files in the Dest directory.

Common options

Delete the file before creating it.             -U; Overwrite the source only the old file is renamed to the file name before the new file--backup-numbered overwrite the target file. Digital

Move command: MV

             使用格式：                           mv [OPTION]... [-T] SOURCE DEST                           mv [OPTION]... SOURCE... DIRECTORY                           mv [OPTION]... -t DIRECTORY SOURCE...

When the source is a file, the target does not exist The Times error is as follows:

mv:missing destination file operand after ' F2 '
Try ' MV--help ' for more information.
When the target is present and is prompted for overwrite when the target is a directory, the source file is moved to the directory

In
When the source is multiple files, the target file times are wrong as follows:
　　　
Mv:target ' T1 ' is not a directory
When the target is a directory, multiple source files are moved to that directory.

When the source is a directory, the target does not exist The Times error is as follows:
mv:missing destination file operand after ' T7 '
Try ' MV--help ' for more information.
When the target exists and is a directory, the source directory is moved to that directory. When the target for file times is wrong as follows:
Mv:overwrite ' passwd '? Y
Mv:cannot overwrite non-directory ' passwd ' with directory ' T7 '

When the source is multiple directories, multiple directories of the source are moved to that directory.

Delete command: RM

                  使用格式：　　rm [OPTION]... FILE...

　　　　
Common options:

             -i 交互式             -f 强制删除             -r 递归删除
