[-Fip@] Source File Target File /Usr/Bin/Cp User Commands cp ( 1 ) NAME cp – copy files SYNOPSIS /usr/bin/cp [-fip@] source_file target_file /usr/bin/cp [-fip@] source_file... target /usr/bin/cp -r -R [-fip@] source_dir... target /usr/xpg4/bin/cp [-fip@] source_file target_file /usr/xpg4/bin/cp [-fip@] source_file... target /usr/xpg4/bin/cp -r -R [-fip@] source_dir... target DESCRIPTION In the first synopsis form, neither source_file nor target_file are directory files, nor can they have the same name. The cp utility will copy the contents of source_file to the destination path named by target_file. If target_file exists, cp will overwrite its contents, but the mode (and ACL if applicable), owner, and group associated with it are not changed. The last modification time of target_file and the last access time of source_file are set to the time the copy was made. If target_file does not exist, cp creates a new file named target_file that has the same mode as source_file except that the sticky bit is not set unless the user is super-user. In this case, the owner and group of target_file are those of the user, unless the setgid bit is set on the directory containing the newly created file. If the directory’s set- gid bit is set, the newly created file will have the group of the containing directory rather than of the creating user. If target_file is a link to another file, cp will overwrite the link destination with the con- tents of source_file; the link(s) from target_file will remain. In the second synopsis form, one or more source_files are copied to the directory specified by target. For each source_file specified, a new file with the same mode (and ACL if applicable), is created in tar- get; the owner and group are those of the user making the copy. It is an error if any source_file is a file of type directory, if target either does not exist or is not a directory. In the third synopsis form, one or more directories specified by source_dir are copied to the directory specified by target. Either -r or -R must be specified. For each source_dir, cp will copy all files and subdirectories. OPTIONS The following options are supported for both /usr/bin/cp and /usr/xpg4/bin/cp: -f Unlink. If a file descriptor for a destination file cannot be obtained, attempt to unlink the desti- nation file and proceed. -i Interactive. cp will prompt for confirmation whenever the copy would overwrite an existing tar- get. A y answer means that the copy should proceed. Any other answer prevents cp from overwriting target. -r Recursive. cp will copy the directory and all its files, including any subdirectories and their files to target. -R Same as -r, except pipes are replicated, not read from. -@ Preserves extended attributes. cp will attempt to copy all of the source file’s extended attributes along with the file data to the destination file. /usr/bin/cp The following option is supported for /usr/bin/cp only: -p Preserve. cp duplicates not only the contents of source_file, but also preserves the owner and group id, permission modes, modification and access time, ACLs, and extended attributes, if applicable. Notice that the command may fail if ACLs are copied to a file system without appropriate support. The command will not fail if unable to preserve extended attributes, modification and access time, or permission modes. If unable to preserve owner and group id, cp SunOS 5.9 Last change: 6 Jun 2001 1 User Commands cp ( 1 ) will not fail, and it will clear S_ISUID and S_ISGID bits in the target. cp will print a diagnostic message to stderr and return a non-zero exit status if unable to clear these bits. In order to preserve the owner and group id, permission modes, and modification and access times, users must have the appropriate file access permissions. This includes being superuser or the same owner id as the destination file. /usr/xpg4/bin/cp The following option is supported for /usr/xpg4/bin/cp only: -p Preserve. cp duplicates not only the contents of source_file, but also preserves the owner and group id, permission modes, modification and access time, ACLs, and extended attributes, if applicable. Notice that the command may fail if ACLs or extended attributes are copied to a file system without appropriate support. If unable to duplicate the modification and access time or the permission modes, cp will print a diagnostic message to stderr and return a non-zero exit status. If unable to preserve owner and group id, cp will not fail, and it will clear S_ISUID and S_ISGID bits in the target. cp will print a diagnostic message to stderr and return a non-zero exit status if unable to clear these bits. In order to preserve the owner and group id, permission modes, and modification and access times, users must have the appropriate file access permissions. This includes being superuser or the same owner id as the destination file. OPERANDS The following operands are supported: source_file A pathname of a regular file to be copied. source_dir A pathname of a directory to be copied. target_file A pathname of an existing or non-existing file, used for the output when a single file is copied. target A pathname of a directory to contain the copied files. USAGE See largefile(5) for the description of the behavior of cp when encountering files greater than or equal to 2 Gbyte ( 2 31 bytes). EXAMPLES Example 1: Copying a file example% cp goodies goodies.old example% ls goodies∗ goodies goodies.old Example 2: Copying a list of files to a destination directory example% cp ˜/src/∗ /tmp Example 3: Copying a directory, first to a new, and then to an existing destination directory example% ls ˜/bkup /usr/example/fred/bkup not found example% cp -r ˜/src ˜/bkup example% ls -R ˜/bkup x.c y.c z.sh SunOS 5.9 Last change: 6 Jun 2001 2 User Commands cp ( 1 ) example% cp -r ˜/src ˜/bkup example% ls -R ˜/bkup src x.c y.c z.sh src: x.c y.c z.s ENVIRONMENT VARIABLES See environ(5) for descriptions of the following environment variables that affect the execution of cp: LC_COLLATE, LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS The following exit values are returned: 0 All files were copied successfully. >0 An error occurred. ATTRIBUTES See attributes(5) for descriptions of the following attributes: /usr/bin/cp_____________________________________________________________________________________ _____________________________________________________________________________________ ATTRIBUTE TYPE ATTRIBUTE VALUE _____________________________________________________________________________________ Availability SUNWcsu _____________________________________________________________________________________ CSI Enabled _____________________________________________________________________________________ Interface Stability Stable /usr/xpg4/bin/cp_____________________________________________________________________________________ _____________________________________________________________________________________ ATTRIBUTE TYPE ATTRIBUTE VALUE _____________________________________________________________________________________ Availability SUNWxcu4 _____________________________________________________________________________________ CSI Enabled _____________________________________________________________________________________ Interface Stability Standard SEE ALSO chmod(1), chown(1), setfacl(1), utime(2), attributes(5), environ(5), fsattr(5), largefile(5), XPG4(5) NOTES The permission modes of the source file are preserved in the copy.

Installation procedures vary slightly depending on the operating system. Refer to the appropriate procedure for your operating system. Domino does not support the HP-UX operating system. Creating symbolic links for the Domino plug-in on Linux and Solaris hosts You need to perform this procedure if you want to create symbolic links for the Domino plug-in on Linux and Solaris hosts. You should not copy and paste commands directly from this document; errors (such as incorrectly transferred characters caused by line breaks and hard returns) might result. Copy and paste the commands into a text editor, verify the commands, and then enter them in the CLI console.

  • Copy — Copy file from Disk Or URL
    Title stata.com copy — Copy file from disk or URL Syntax Description Options Remarks and examples Also see Syntax copy filename1 filename2 , options filename1 may be a filename or a URL. filename2 may be the name of a file or a directory. If filename2 is a directory name, filename1 will be copied to that directory. filename2 may not be a URL. Note: Double quotes may be used to enclose the filenames, and the quotes must be used if the filename contains embedded blanks. options Description public make filename2 readable by all text interpret filename1 as text file and translate to native text format replace may overwrite filename2 replace does not appear in the dialog box. Description copy copies filename1 to filename2. Options public specifies that filename2 be readable by everyone; otherwise, the file will be created according to the default permissions of your operating system. text specifies that filename1 be interpreted as a text file and be translated to the native form of text files on your computer. Computers differ on how end-of-line is recorded: Unix systems record one line-feed character, Windows computers record a carriage-return/line-feed combination, and Mac computers record just a carriage return. text specifies that filename1 be examined to determine how it has end-of-line recorded and that the line-end characters be switched to whatever is appropriate for your computer when the copy is made. There is no reason to specify text when copying a file already on your computer to a different location because the file would already be in your computer’s format.

  • Mac Keyboard Shortcuts Cut, Copy, Paste, and Other Common Shortcuts
    Mac keyboard shortcuts By pressing a combination of keys, you can do things that normally need a mouse, trackpad, or other input device. To use a keyboard shortcut, hold down one or more modifier keys while pressing the last key of the shortcut. For example, to use the shortcut Command-C (copy), hold down Command, press C, then release both keys. Mac menus and keyboards often use symbols for certain keys, including the modifier keys: Command ⌘ Option ⌥ Caps Lock ⇪ Shift ⇧ Control ⌃ Fn If you're using a keyboard made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command. Some Mac keyboards and shortcuts use special keys in the top row, which include icons for volume, display brightness, and other functions. Press the icon key to perform that function, or combine it with the Fn key to use it as an F1, F2, F3, or other standard function key. To learn more shortcuts, check the menus of the app you're using. Every app can have its own shortcuts, and shortcuts that work in one app may not work in another. Cut, copy, paste, and other common shortcuts Shortcut Description Command-X Cut: Remove the selected item and copy it to the Clipboard. Command-C Copy the selected item to the Clipboard. This also works for files in the Finder. Command-V Paste the contents of the Clipboard into the current document or app. This also works for files in the Finder. Command-Z Undo the previous command. You can then press Command-Shift-Z to Redo, reversing the undo command.

  • Timestamp Changes in Case of Copy Command (Win7, Win10)
    Timestamp changes in case of copy command (Win7, Win10) Investigating timestamp differences between Windows 7 and Windows 10. I intended to figure out how MACB timestamps of the original and the newly created files are changing during a file copy in Windows. I also checked the differences between the results of the GUI based copy and paste method and the command line based copy command. I compared the changes in case of an in-volume copy and in case of copying to a different volume as well. Tools: These are the tools that were used during my investigation. • Microsoft Windows 10 64-bit v10.0.17134.345 • Microsoft Windows 7 Enterprise SP1 • FTK Imager 4.2 - for creating images about the drives and to save the MFT file • analyzeMFT.py - for MFT parsing (https://github.com/dkovar/analyzeMFT) MACB An NTFS volume stores 8 different timestamps for a single file. These timestamps are the followings: • Modified • Accessed • Changed (Info Entry date change) • Birth (file creation time) All of these 4 information snippets are stored in the $STANDARD_INFO and in the $FILE_NAME as well. The difference between the two attributes: • $STANDARD_INFO: can be modified by user level processes. Therefore it can be altered by anti-forensics utilities. • $FILE_NAME: can only be modified by the system kernel. No known anti-forensics tools can modify it. Method of investigation 1) I generated two files in an NTFS volume. 2) Copied one of the files with copy paste and the other one with copy command from command line into a different directory. 3) Generated two files in an NTFS volume to test out-of-volume copy.
