Understanding the cp Command

Basic Usage of cp

The cp command is used to copy files and directories in Linux. The most basic usage is:

cp [source_file] [destination]

This will copy the specified file from the source to the destination.

Options Available with cp

cp (Basic Copy)

Copies a file or directory from one location to another:

cp file1.txt /home/user/directory/

cp -r (Recursive Copy)

Copies directories recursively (i.e., it copies the directory along with all its files and subdirectories):

cp -r directory1/ /home/user/directory2/

cp -f (Force Overwrite)

Forces the overwrite of existing files without confirmation:

cp -f file1.txt /home/user/directory/

cp -i (Interactive Mode)

Prompts the user for confirmation before overwriting files:

cp -i file1.txt /home/user/directory/

cp -u (Update Only)

Copies only when the source file is newer than the destination file or if the destination file does not exist:

cp -u file1.txt /home/user/directory/

cp -v (Verbose Output)

Displays detailed information about the copying process:

cp -v file1.txt /home/user/directory/

cp -p (Preserve File Attributes)

Preserves file attributes such as modification time, access time, and file permissions:

cp -p file1.txt /home/user/directory/

cp -a (Archive Mode)

Preserves the original file structure, attributes, and symbolic links while copying directories recursively:

cp -a directory1/ /home/user/directory2/

cp --parents

Copies the file along with its parent directory structure:

cp --parents dir1/dir2/file.txt /destination/

cp -n (No Overwrite)

Prevents overwriting existing files at the destination:

cp -n file1.txt /home/user/directory/
