cp Command Cheatsheet

The cp command in Unix/Linux is used to copy files and directories. It stands for "copy" and can be utilized for various file management tasks. Below are the basic and advanced usages of the cp command along with practical examples.

Basic Usage

• Copy a file to another directory

    cp source_file /destination/directory/
  

• Copy and rename a file

    cp source_file /destination/directory/new_filename
  

Common Options

• Interactive mode (prompt before overwrite)

    cp -i source_file /destination/directory/
  

• Force copy without prompting

    cp -f source_file /destination/directory/
  

• Verbose mode (show what is being done)

    cp -v source_file /destination/directory/
  

• Recursive copy (copy directories and their contents)

    cp -r source_directory /destination/directory/
  

• Preserve file attributes (ownership, timestamps, etc.)

    cp -p source_file /destination/directory/
  

• Update only if the source file is newer

    cp -u source_file /destination/directory/
  

• Create hard links instead of copying

    cp -l source_file /destination/directory/
  

• Create symbolic links instead of copying

    cp -s source_file /destination/directory/
  

Examples

• Copy a single file

    cp file.txt /home/user/Documents/
  

• Copy and rename a file

    cp file.txt /home/user/Documents/new_file.txt
  

• Copy multiple files to a directory

    cp file1.txt file2.txt file3.txt /home/user/Documents/
  

• Copy a directory recursively

    cp -r /home/user/Downloads /home/user/Documents/
  

• Interactive copy (prompt before overwrite)

    cp -i file.txt /home/user/Documents/
  

• Verbose copy

    cp -v file.txt /home/user/Documents/
  

Advanced Usage

• Copy all files with a specific extension

    cp *.txt /home/user/Documents/
  

• Copy files using a wildcard and rename

    cp *2023.log /home/user/Logs/
  

• Copy and overwrite only if the source file is newer

    cp -u file.txt /home/user/Documents/
  

• Preserve file attributes during copy

    cp -p file.txt /home/user/Documents/
  

• Create a hard link to a file

    cp -l file.txt /home/user/Documents/
  

• Create a symbolic link to a file

    cp -s file.txt /home/user/Documents/
  

Practical Tips

• Safety First: Use the -i option to prevent accidental overwrites.

• Preserve Attributes: Use the -p option to maintain file attributes.

• Verbose Mode: Use -v to see exactly what cp is doing, useful for debugging scripts.

• Recursive Copy: Always use -r when copying directories to ensure all contents are copied.

Quick Reference

• Copy a file:

    cp source_file /destination/directory/
  

• Copy and rename a file:

    cp source_file /destination/directory/new_filename
  

• Interactive mode:

    cp -i source_file /destination/directory/
  

• Force copy:

    cp -f source_file /destination/directory/
  

• Verbose mode:

    cp -v source_file /destination/directory/
  

• Recursive copy:

    cp -r source_directory /destination/directory/
  

• Preserve file attributes:

    cp -p source_file /destination/directory/
  

• Update only if newer:

    cp -u source_file /destination/directory/
  

• Create hard link:

    cp -l source_file /destination/directory/
  

• Create symbolic link:

    cp -s source_file /destination/directory/
