Similar to fgrep on Linux, FIND prints lines that contain a string. If you need to find text in a file, the FIND command does the job. If HELLO.TXT doesn't exist yet, then EDIT starts a new file for you. If the HELLO.TXT file already exists, EDIT opens the file for editing. For example, to start editing a file called HELLO.TXT, type EDIT HELLO.TXT. If you need to edit a text file on FreeDOS, the EDIT program lets you do that quickly and easily. You can easily and quickly wipe out a lot of work with a single DELTREE command, so the FreeDOS DELTREE prompts you to ask if this is really something you want to do. For example, to delete your FILES directory, including all the files and directories it contains, type this command: C:\>deltree files You can delete an entire directory tree with the DELTREE command. But what if you want to delete a directory that has lots of files and subdirectories inside it?Ī directory with other directories inside it is called a directory tree. To remove an empty directory, you can use the RMDIR or RD commands. If you need to delete a single file, you can use the DEL command. You can instead provide the full directory path you want to change to, with one CD command: C:\>cd \files\sprdshtĢ dir(s) 279,527,424 bytes free D is for DELTREE You don't have to navigate one directory at a time. To change into a new directory, use the CD command with the destination directory: C:\>cd files The CHDIR command is the same as CD, if you prefer to use that syntax. You can navigate into a directory using the CD or change directory command. For example, you might keep all of your files in a directory called FILES, and you might have other directories inside FILES for certain kinds of files, such as DOCS for word processor files, or SPRDSHT for spreadsheet files. Like Linux, FreeDOS supports directories, which allow you to organize your files in a way that makes sense to you. If you boot FreeDOS using a virtual machine, check that your system is set up to correctly emulate the PC speaker. Note that BEEP uses the PC's built-in speaker to make the “beep” sound. BEEP doesn't display anything to the screen, but simply generates a classic “beep” tone. If you need to add a little pizzazz to a batch file, you can use the BEEP command to get the user's attention. Turn on the Read-only attribute like this, with the +R modifier: C:\FILES>attrib +r secret.txtĬheck out more cheat sheets B is for BEEP Suppose you want to protect the SECRET.TXT file so you can't delete or change it. To hide this file, turn on the Hidden attribute by using the plus ( +) operator, like this: C:\FILES>attrib +h secret.txtĪnother common way to use ATTRIB is by manipulating the Read-only attribute, so you don't accidentally overwrite an important file. First, you can show the attributes on that file to see its current settings: C:\FILES>attrib secret.txt For example, suppose you want to "hide" a file called SECRET.TXT so no one would know it was there. An attribute can be one of four values: Hidden (H), System (S), Read-only (R), and Archive (A).įiles marked as Hidden don't display in a directory listing. The ATTRIB program displays or changes a file's attributes. D Process directory names for arguments with Process files, listed in the specified file. S Process files in all directories in the specified path(es). To learn more, add the /? option after most commands to get more information: C:\>attrib /?ĪTTRIB v2.1 - Displays or changes file attributes.Ĭopyright (c) 1998-2003, licensed under GPL2. Let's get started with 26 of my favorite FreeDOS commands. If you're new to FreeDOS, you may be confused about how to use the different command line programs that come with it. Today on June 29, we celebrate 28 years of FreeDOS. We loved DOS so much that in 1994, we created the FreeDOS Project. SetConsoleMode(h, mode.One of my family's first computers ran a command-line operating system called DOS, the "Disk Operating System." I grew up with DOS, and learned to leverage the command line to make my work easier. If (mode.value & ENABLE_VIRTUAL_TERMINAL_PROCESSING) = 0: If (GetFileType(h) & 3) != FILE_TYPE_CHAR:ĮNABLE_VIRTUAL_TERMINAL_PROCESSING = 0x0004 POINTER(DWORD))(('GetConsoleMode', windll.kernel32))ĭWORD)(('SetConsoleMode', windll.kernel32)) HANDLE)(('GetFileType', windll.kernel32)) """Enable Windows 10 cmd.exe ANSI VT Virtual Terminal Processing."""įrom ctypes import byref, POINTER, windll, WINFUNCTYPEįrom ctypes.wintypes import BOOL, DWORD, HANDLEĭWORD)(('GetStdHandle', windll.kernel32)) Pass in argument value 1 for stdout or 2 stderr. Enables ANSI VT mode (virtual terminal processing) on Windows 10. This adaptation of some code I proposed here should help get you started.
