[Linux] C Shell (csh) cp Uso: Copy files and directories

Overview

The cp command in C Shell (csh) is used to copy files and directories from one location to another. It allows users to duplicate files or entire directories while maintaining the original files intact.

Usage

The basic syntax for the cp command is as follows:

cp [options] [source] [destination]

Common Options

• -i: Prompts before overwriting an existing file.
• -r: Recursively copies directories and their contents.
• -u: Copies only when the source file is newer than the destination file or when the destination file is missing.
• -v: Verbosely lists files being copied.

Common Examples

Here are some practical examples of using the cp command:

1. Copy a single file:

   cp file1.txt file2.txt
   

   This command copies file1.txt to file2.txt.

2. Copy a directory recursively:

   cp -r dir1 dir2
   

   This command copies the entire directory dir1 and its contents to dir2.

3. Copy a file with prompt before overwrite:

   cp -i file1.txt file2.txt
   

   This command will ask for confirmation before overwriting file2.txt if it already exists.

4. Copy only newer files:

   cp -u file1.txt file2.txt
   

   This command copies file1.txt to file2.txt only if file1.txt is newer or if file2.txt does not exist.

5. Verbose copy:

   cp -v file1.txt file2.txt
   

   This command will display a message indicating that file1.txt is being copied to file2.txt.

Tips

• Always use the -i option if you’re unsure about overwriting files to avoid accidental data loss.
• When copying directories, remember to use the -r option to ensure all contents are copied.
• Use the -v option for a clearer understanding of what files are being copied, especially when dealing with multiple files or directories.
