How To Copy Files With Same Permissions In Unix You Combine![]() Creates a copy of the file in the working directory named origfile. The copy will be named newfile, and will be located in the working directory. CAREFUL! If the destination file newfile already exists, it will be overwritten without a confirmation prompt. This is the default behavior for all cp operations. If you want to be prompted before overwriting a file, use the - i (interactive) option. For example: cp - i oldfile newfile. If newfile already exists, you will be prompted: cp: overwrite ‘newfile’? If you type y (or yes, Y, YES, or any other combination of upper and lowercase of these), then newfile will be overwritten with a copy of origfile. Typing anything else will abort the operation. Copy a file into another directory: cp origfile /directory/subdirectory. Creates a copy of the file in the working directory named origfile. The copy will be located in the directory /directory/subdirectory, and will be named origfile. Same as the above command. The slash- dot ("/.") is implied in the above form of the command. The dot is a special file in every Linux directory which means "this directory.")Copy a file into another directory, and give it a new name: cp origfile /directory/subdirectory/newfile. Creates a copy of the file in the working directory named origfile. The copy will be named newfile, and will be located in the directory /directory/subdirectory. Copy multiple files into another directory, using a wildcard: cp file* /directory/subdirectory. Copy every file in the working directory whose name begins with file into the directory /directory/subdirectory. The asterisk ("*") is a wildcard — a special character which expands to match other characters. Specifically, the asterisk wildcard matches zero or more non- whitespace characters. For instance, this command will copy any files named file, file. Copy every file in the working directory whose name begins with file, and ends with the file extension . For instance, it would make copies of any files named file, file. The copies will be placed into the directory /directory/subdirectory. Copy an entire directory structure into another location: cp - R /one/two /three/four. Copy the directory two (located in the directory /one), and everything two contains, into the destination directory /three/four. The result will be called /three/four/two. The directory /three must already exist for the command to succeed. If the directory four does not already exist in the directory /three, it will be created. General Overview. Let's say you have a file named picture. You would run the command: cp picture. Here, picture. jpg is the source of the copy operation, and picture- 0. Both files now exist in your working directory. The source and destination files may also reside in different directories. For instance,cp /home/chuck/pictures/picture. The destination file will also be named picture. If you are the user chuck, you can abbreviate your home directory ("/home/chuck") using a tilde ("~"). For instance,cp ~/pictures/picture. Copying Multiple Files To A Directory Or, perhaps you want to copy multiple files into another directory. To accomplish this, you can specify multiple files as the source, and a directory name as the destination. Let's say you are the user sally, and you have a bunch of files in the directory /home/sally/pictures/ named picture- 0. This command will do the trick: cp ~/pictures/picture- *. Here, we use a wildcard (the asterisk, "*") to indicate that the source files are all the files in the directory /home/sally/pictures whose name starts with "picture- " and has the extension ". They will be copied into the directory /home/sally/picture- backup, assuming that directory already exists. If it doesn't exist, cp will give you an error message, and no files will be copied. You can also specify multiple source files one after the other, and cp will expect that the final argument is a directory name, and copy them all there. For instance,cp ~/pictures/picture- 0. Copying Files Recursively. You can use cp to copy entire directory structures from one place to another using the - R option to perform a recursive copy. Let's say you are the user steve and you have a directory, /home/steve/files, which contains many files and subdirectories. You want to copy all those files, and all the subdirectories (and the files and subdirectories they contain), to a new location, /home/steve/files- backup. You can copy all of them using the command: cp - R ~/files ~/files- backup.. When performing a recursive copy: if the directory files- backup already exists, the directory files will be placed inside; if files- backup does not already exist, it will be created and the contents of the files directory will be placed inside it. Creating Symbolic Links Instead Of Copying Data. Another useful trick is to use cp to create symbolic links to your source files. You may already be familiar with using the ln command to create symlinks; cp is a great way to create multiple symlinks all at once. So, for instance,cp - s file. You can also create symbolic links from multiple source files, specifying a directory as the destination. Note: To create symbolic links in another directory, cp needs you to specify the full pathname, including the full directory name, in your source filename(s). Relative paths will not work. Let's say you are user melissa and you have a set of files, file. You want to create symbolic links to these files in the existing directory /home/melissa/myfiles. This command will do the trick: cp - s ~/myfiles/file*. The directory myfiles. The myfiles. 2 directory must already exist for the operation to succeed; if it doesn't exist, cp will give you an error message and nothing will be copied. This will work with a recursive copy, as well. So the command: cp - R - s ~/myfiles ~/myfiles. If myfiles. 2 already exists, cp will create a directory inside it called myfiles which contains the directory structure and symlinks; if myfiles. There are many other options you can provide to cp which will affect its behavior. These are listed, along with the precise command syntax, in the following sections. Options. In accordance with the command syntax above, cp copies the source file SOURCE to the destination file DEST, or multiple SOURCE file(s) to destination directory DIRECTORY. If specified, the following OPTIONs modify the behavior of the operation: -a, - -archive. Same as - d. R - -preserve=ALL.- -attributes- only. Don't copy the file data, just create a file with the same attributes.- -backup[=CONTROL]Make a backup of each existing destination file. CONTROL specifies the version control method to use; see below for more details.- b. Like - -backup, but does not accept a CONTROL argument; the default control method is always used.- -copy- contents. When operating recursively, copy contents of special files.- d. Same as - -no- dereference - -preserve=links.- f, - -force. If an existing destination file cannot be opened, remove it and try again. This option has no effect if the - n option is used.- i, - -interactive. Prompt before overwrite (overrides a previous - n option).- HFollow command- linesymbolic links in SOURCE.- l, - -link. Create hard links to files instead of copying them.- L, - -dereference. Always follow symbolic links in SOURCE. In other words, if SOURCE is a symlink, copy the file linked to rather than the symlink itself.- n, - -no- clobber. Do not overwrite an existing file (overrides a previous - i option).- P, - -no- dereference. Never follow symbolic links in SOURCE.- p. Same as - -preserve=mode,ownership,timestamps.- -preserve=[ATTR_LIST]Preserve the specified attributes (default: mode,ownership,timestamps), if possible additional attributes: context, links, xattr, all.- -no- preserve=ATTR_LISTDon't preserve the specified attributes.- -parents. Use full source file name under DIRECTORY.- R, - r, - -recursive. Copy directories recursively.- -reflink=[WHEN]Control clone/Co. W copies.- -remove- destination. Remove each existing destination file before attempting to open it (contrast with the - -force option).- -sparse=WHENControl 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=SUFFIXOverride the usual backup suffix.- t, - -target- directory=DIRECTORYCopy all SOURCE arguments into DIRECTORY- T, - -no- target- directory. Treat DEST as a normal file- u, - -update. Copy only when the SOURCE file is newer than the destination file or when the destination file is missing.- v, - -verbose. Verbose mode; explain what is being done.- x, - -one- file- system. Stay on this file system.- -help. Display a help message and exit.- -version. Output version information and exit. By default, sparse SOURCE files are detected by a crude heuristic and the corresponding DEST file is made sparse as well. That is the behavior selected by - -sparse=auto. Specify - -sparse=always to create a sparse DEST file whenever the SOURCE file contains a long enough sequence of zero bytes. Use - -sparse=never to inhibit creation of sparse files. When - -reflink[=always] is specified, cp performs a lightweight copy, where the data blocks are copied only when modified. If this is not possible, the copy fails; or, if - -reflink=auto is specified, cp falls back to a standard copy operation. The backup suffix is '~', unless set with - -suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the - -backup=CONTROL option or through the VERSION_CONTROLenvironment variable.
