Commonly Used Options
-i(interactive): Prompts before overwriting an existing file to prevent accidental data loss.
Example:
cp -i file.txt /path/to/destination/
-u(update): Copies only if the source file is newer than the destination file or if the destination file does not exist.
Example:
cp -u file.txt /path/to/destination/
-v(verbose): Displays the detailed output of the copying process, showing each file copied.
Example:
cp -v file.txt /path/to/destination/
-p(preserve): Retains file attributes such as timestamps, ownership, and permissions.

cp Command in Linux Examples
Here are different uses of the cp command in Linux with examples:
1. Copy a Single File
To copy a file to another directory:
cp file.txt /home/user/documents/
This copies file.txt to the documents directory.
2. Copy Multiple Files
To copy multiple files to a directory:
cp file1.txt file2.txt /home/user/documents/
This copies both file1.txt and file2.txt to the documents directory.
3. Copy Directories Recursively
To copy an entire directory, use the -r option:
cp -r /home/user/source_directory /home/user/backup/
This copies the entire source_directory and its contents to backup.
4. Copy Files While Preserving Attributes
To retain original file attributes like timestamps and permissions:
cp -p file.txt /home/user/documents/
This ensures that the copied file retains its original attributes.
5. Copy Files with Wildcards
To copy all .txt files in the current directory to another location:
cp *.txt /home/user/documents/
This command copies all text files to the documents directory.
