fileBatch Copying Files with Linux: cp a r（linuxcpar）

One of the most common tasks performed in the Linux command line is the ability to quickly and efficiently copy multiple files into new locations. This article provides a detailed guide for using the command line to copy multiple files with Linux: cp, a, and r.

The cp command is the most popular way to copy files in Linux. It is a simple command that can be used to copy, move, and delete files and directories. To use the cp command, specify the source and destination files as arguments. For example, to copy the file test.txt from the current directory to the directory Documents/, use the command “cp test.txt Documents/”. It’s also possible to copy multiple files to a single destination directory. To do this, specify the source files followed by a single destination directory. For example, the command “cp file1.txt file2.txt Documents/” will copy both files to the destination directory.

The a command is used to append files from one directory to another. This command will add the contents of a new file to the end of an existing file in the destination directory. To use the a command, specify the source file followed by the destination file as arguments. For example, to append the file test.txt to the file documents.txt in the directory Documents/, use the command “a test.txt documents.txt Documents/”.

The r command is used to recursively copy files from one directory to another. This command will copy all of the files and sub-directories from the source directory to the destination directory. To use the r command, specify the source and destination directories as arguments. For example, to recursively copy all of the files and sub-directories from the directory Documents/** to the directory Documents/backup/, use the command “r Documents/** Documents/backup/”.

Batch copying files in Linux is a simple and straightforward process. Using the commands cp, a, and r, you can be quickly and efficiently copy files from one directory to another. By following the examples above, you can master the Linux command line and take advantage of the powerful programmable interface available to Linux users.
