This article mainly introduces the Linux commonly used command cp how to use, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Linux common command cp command is also a very commonly used command in our actual use, mainly used to copy files, folders and so on.

Syntax cp [options] source dest or

Cp [options] source... Directory parameter description:

-a: this option is usually used when copying a directory, preserving links, file properties, and copying everything in the directory. Its function is equal to the combination of dpR parameters.

-d: keep the link when copying. The links mentioned here are equivalent to shortcuts in the Windows system.

-f: overwrite existing target files without prompting.

-I: contrary to the-f option, prompt the user to confirm whether or not to overwrite the target file before overwriting, and the target file will be overwritten when answering y.

-p: copy the modification time and access rights to the new file in addition to copying the contents of the file.

-r: if the source file given is a directory file, all subdirectories and files under that directory will be copied.

-l: do not copy the file, just generate the linked file.

Example 1) copy file1 to another location

# cp file1.. / destDir/ # ls.. / destDir/ file12) copy the entire folder to another folder

Ls destDir testDir # cp-r testDir destDir # ls destDir file1 testDir3) forces the target file to be overwritten without asking

# cp-r testDir destDir cp: overwrite `destDir/testDir/file2'? Y cp: overwrite `destDir/testDir/file1'? Y cp: overwrite `destDir/testDir/file3'? Y # cp-nrf testDir destDir # using the-n option ignores override queries. Cp is an alias for cp-I, and the default is to prompt whether to overwrite, so you need to add the-n option.

4) copy a link for file1

Cp-s file1 file1_link # ll total 4-rw-r--r-- 1 root root 0 Jun 13 14:18 file3-rw-r--r-- 1 root root 74 Jun 13 15:37 file1-rw-r--r-- 1 root root 0 Jun 13 15:39 file2 lrwxrwxrwx 1 root root 5 Jun 14 21:44 file1_link-> file1 # cat file1_link This is a test file. Welcome to linuxdaxue.com! This is cat command test. This example copies a link for file1, and the contents of file1_link and file1 are the same.

The cp command we mainly use in our actual work is cp or cp-r, and the other commands are not commonly used, but we also need to master them so as not to check them again when we use them.
