While working on development projector support activities  in Linux operation system , I often need to  backup the current working folder /directory before many any changes. Let’s see how we can do accomplished that.

How to copy Files/folder from One place to another in Linux Operating system

Linux Operating system provides cp command to copy the files/directory from one place to another  and mv command to move the file/directory. Apart of these we can also use rsync utility to  perform copy and backup.

Each of these command has various options to copy the directory

I would explaining each command in details here with many examples

cp  copy files/dirs

This  command is used in Unix/Linux Operation system to copy the files and directory

 

cp General Options:
-i Interactive. cp will prompt for confirmation whenever the copy would overwrite an existing target.
-r Recursive. cp will copy the directory and all its files, including any subdirectories and their files to target.
-p Preserve. cp duplicates not only the contents of source_file, but also preserves the owner and group id, permissions modes, modification and access time.
More Options:
-v verbose. cp will show all the file being copied.
-u copy only if the source file is newer
–backup This option will make backup copy of the file in destination side.–backup=simple option will create a backup file which marked by a tilde sign (~)–attributes-only  This option will copy file with zero bytes and same attribute as source file-f  Force option.  it will force the copying activity. If the destination files cannot be opened, then -f will try again.-a  archive option. It will copy the directory with exact files and directory including symbolic link-L copy without following symbolic link in source-P copy following symbolic link in source

How it works for General option

If directory d2 does not exist, it is created. Otherwise, it creates a directory named d1 within directory d2.

Command Results
cp x y Copies the contents of x into y. If y does not exist, it is created; otherwise, y is overwritten with the contents of x.
cp -i x y Like above however, since the “-i” (interactive) option is specified, if y exists, the user is prompted before it is overwritten with the contents of x.
cp x d1 Copy the contents of x (into a file named x) inside of directory d1.
cp -R d1 d2 Copy the contents of the directory d1.
