About cp

Copies files from one location to another.

Syntax

cp [OPTION]... SOURCE DEST
cp [OPTION]... SOURCE... DIRECTORY
cp [OPTION]... --target-directory=DIRECTORY SOURCE...

-a, --archive same as -dpR
--backup[=CONTROL] make a backup of each existing destination file
-b like --backup but does not accept an argument
--copy-contents copy contents of special files when recursive
-d same as --no-dereference --preserve=link
--no-dereference never follow symbolic links
-f, --force if an existing destination file cannot be opened, remove it and try again
-i, --interactive prompt before overwrite
-H follow command-line symbolic links
-l, --link link files instead of copying
-L, --dereference always follow symbolic links
-p same as --preserve=mode,ownership,timestamps
--preserve[=ATTR_LIST] preserve the specified attributes (default: mode,ownership,timestamps), if possible additional attributes: links,
all
--no-preserve=ATTR_LIST don't preserve the specified attributes
--parents append source path to DIRECTORY
-P same as '--no-dereference'
-R, -r, --recursive copy directories recursively
--remove-destination remove each existing destination file before attempting to open it (contrast with --force)
--reply={yes,no,query} specify how to handle the prompt about an existing destination file
--sparse=WHEN control creation of sparse files
--strip-trailing-slashes remove any trailing slashes from each SOURCE argument
-s, --symbolic-link make symbolic links instead of copying
-S, --suffix=SUFFIX override the usual backup suffix
--target-directory=DIRECTORY move all SOURCE arguments into DIRECTORY
-u, --update copy only when the SOURCE file is newer than the destination file or when the destination file is missing
-v, --verbose explain what is being done
-x, --one-file-system stay on this file system

Examples

cp file1.txt newdir

Copies the file1.txt in the current directory to the newdir directory.

cp /home/public_html/mylog.txt /home/public_html/backup/mylog.bak

Copies the mylog.txt file in the public_html directory into the public_html/backup directory as mylog.bak. The files are identical however have different names.

cp *.txt newdir

Copy all files ending in .txt into the newdir directory.

cp -r /home/hope/files/* /home/hope/backup

Copies all the files, directories, and subdirectories in the files directory into the backup directory.

yes | cp /home/hope/files/* /home/hope/files2

Copies all the files and subdirectories in files into the files2 directory. If files with the same name exist or it's prompted to overwrite the file it answers yes.

Additional information

Many new versions of Linux/Unix or their variants may also be able to use copy in place of cp or have an alias setup for cp as copy.

What's the difference between "include" and "require" in Ruby?

By -
The include and require methods do very different things. The require method does what include does in most other programming languages: run another file. It also tracks what you've required in the past and won't require the same file twice. To run another file without this added functionality, you can use the load method. The include method takes all the methods from another module and includes them into the current module. This is a language-level thing as opposed to a file-level thing as with require. The include method is the primary way to "extend" classes with other modules (usually referred to as mix-ins). For example, if your class defines the method "each", you can include the mixin module Enumerable and it can act as a collection. This can be confusing as the include verb is used very differently in other languages.
