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
-I: Interactive prompt On overlay-r: Recursively copy all contents of directory and directory-D: When not added-D , the copy soft link will copy the content from the source, plus the-D to keep the link property, copy the soft link past--preserve= Property list Mode: Indicates permission invariant Owner[ship]: Indicates permission and the owner and the group are unchanged Time: three timestamp unchanged Xattr: Indicates ACL permissions are not changed Links: Indicates that the link is unchanged Context: Indicates that the security context of the file does not change All: Represents all of the above properties-P: means to keep the properties of the original file-A: Represents the archive, equivalent to-RDP -V: Shows the replication process-F: Force overwrite: When a normal user is not able to change the target file, but has permission to create and delete files in the directory where the target file resides, use-F can be used to force the overwrite. 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.
