cp

Command Function

This command is used to create a copy for a file.

Syntax

cp [SOURCEFILE] [DESTFILE]

Parameters

Table 1 Parameter description

Parameter	Description	Value Range
–help	Displays help information.	N/A
SOURCEFILE	Specifies the file to copy.	This command does not support copy of a directory, but supports copy of multiple files at a time.
DESTFILE	Specifies the file to create.	Both a directory and a file are supported.

Usage Guidelines

The name of the source file cannot be the same as that of the destination file in the same path.
SOURCEFILE must exist and cannot be a directory.
The source file path supports asterisks (*) and question marks (?). The wildcard “*” indicates any number of characters, and “?” indicates any single character. DEST does not support wildcard characters. If the specified SOURCE matches multiple files, DEST must be a directory.
If DEST is a directory, this directory must exist. In this case, the destination file is named after the source file.
If the destination file path is a file, the directory for this file must exist. In this case, the file copy is renamed.
If the destination file does not exist, a new file is created. If the destination file already exists, the existing file is overwritten.

NOTICE
When important system resources are copied, unexpected results such as a system breakdown may occur. For example, when the /dev/uartdev-1 file is copied, the system may stop responding.

Example

Run cp hello-OHOS.txt hello-openharmony.txt ./tmp/.
