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. -
Windows Command Prompt Cheatsheet
Windows Command Prompt Cheatsheet - Command line interface (as opposed to a GUI - graphical user interface) - Used to execute programs - Commands are small programs that do something useful - There are many commands already included with Windows, but we will use a few. - A filepath is where you are in the filesystem • C: is the C drive • C:\user\Documents is the Documents folder • C:\user\Documents\hello.c is a file in the Documents folder Command What it Does Usage dir Displays a list of a folder’s files dir (shows current folder) and subfolders dir myfolder cd Displays the name of the current cd filepath chdir directory or changes the current chdir filepath folder. cd .. (goes one directory up) md Creates a folder (directory) md folder-name mkdir mkdir folder-name rm Deletes a folder (directory) rm folder-name rmdir rmdir folder-name rm /s folder-name rmdir /s folder-name Note: if the folder isn’t empty, you must add the /s. copy Copies a file from one location to copy filepath-from filepath-to another move Moves file from one folder to move folder1\file.txt folder2\ another ren Changes the name of a file ren file1 file2 rename del Deletes one or more files del filename exit Exits batch script or current exit command control echo Used to display a message or to echo message turn off/on messages in batch scripts type Displays contents of a text file type myfile.txt fc Compares two files and displays fc file1 file2 the difference between them cls Clears the screen cls help Provides more details about help (lists all commands) DOS/Command Prompt help command commands Source: https://technet.microsoft.com/en-us/library/cc754340.aspx. -
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. -

TB-1052 Digital Video Systems
IRIS TECHNICAL BULLETIN TB-1052 Digital Video Systems Subject: Installing and Running Check Disk on XP Embedded Systems Hardware: TotalVision-TS Software: IRIS DVS XPe Ver. 11.04 and Earlier (Including FX and non-FX Units) Release Date: 12/22/08 SUMMARY IRIS DVS units initially produced prior to January 1, 2009 may not have complete support for running chkdsk.exe even though the chkdsk.exe file exist in the Windows/System32 directory. This Technical Bulletin describes how to install and run the Check Disk (ChkDsk) utility to minimize file corruption problems and potential RAW Disk failures. INSTALLING SOFTWARE Several additional files are needed to be installed on the DVS hard drive. You can get a copy of these files at the IRIS Web Service Site www.SecurityTexas.com/service. Download the “Check Disk Upgrade” package and follow the instructions in the ReadMe file of that zip file on how to upgrade the files on the DVS. Once the files are copied to the hard drive, highlight the file “EVENTVWR.MSC” and then select “File- >Pin to Start Menu” to provide an easy way to access the Event Viewer. After the required software has been installed run Windows File Explorer and select the C:\BankIRIS_NT directory. Double-click on the AUTOCHECK.REG file. Answer YES in response to the two prompts to update the registry. Expert Mode: To verify that the registry changes were done you can select “Start->Run” and type in “RegEdit.exe” to run the Registry Editor. Select the key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Sesion Manager”. Select the key "BootExecute". -
