1. Cmd Commands For Hacking

I can understand cmd but not cmd /c. I was trying to invoke a java program from the current for which I use Runtime.getRuntime.exec('cmd /C java helloworld'); There arises my doubt. Cmd c is a clipboard manager designed to meet the needs of code developers: it will preserve the text formatting, allows you to navigate its history using the keyboard, and even keeps windows in memory for 5 minutes. Open command prompt. Go to Windows search and type cmd. Right-click on the command prompt. How to Compile C Program in Command Prompt? STEP 1: Run the command ‘gcc -v’ to check if you have a compiler installed. If not you need to download a gcc compiler and install it. You can search for cmd in your windows system to open the command prompt. STEP 2: Create a c program and store it in your system.

Selects and runs a command on a file or set of files. This command is most commonly used in batch files.

Syntax

Parameters

Parameter	Description
/P <pathname>	Specifies the path from which to start the search. By default, searching starts in the current working directory.
/M <searchmask>	Searches files according to the specified search mask. The default searchmask is *.
/S	Instructs the forfiles command to search in subdirectories recursively.
/C <command>	Runs the specified command on each file. Command strings should be wrapped in double quotes. The default command is 'cmd /c echo @file'.
/D [{+|-}][{<date> | <days>}]	Selects files with a last modified date within the specified time frame: Selects files with a last modified date later than or equal to (+) or earlier than or equal to (-) the specified date, where date is in the format MM/DD/YYYY. Selects files with a last modified date later than or equal to (+) the current date plus the number of days specified, or earlier than or equal to (-) the current date minus the number of days specified. Valid values for days include any number in the range 0–32,768. If no sign is specified, + is used by default.
/?	Displays the help text in the cmd window.

Remarks

• The forfiles /S command is similar to dir /S.

• You can use the following variables in the command string as specified by the /C command-line option:

  Variable	Description
  @FILE	File name.
  @FNAME	File name without extension.
  @EXT	File name extension.
  @PATH	Full path of the file.
  @RELPATH	Relative path of the file.
  @ISDIR	Evaluates to TRUE if a file type is a directory. Otherwise, this variable evaluates to FALSE.
  @FSIZE	File size, in bytes.
  @FDATE	Last modified date stamp on the file.
  @FTIME	Last modified time stamp on the file.

• The forfiles command lets you run a command on or pass arguments to multiple files. For example, you could run the type command on all files in a tree with the .txt file name extension. Or you could execute every batch file (*.bat) on drive C, with the file name Myinput.txt as the first argument.

• This command can:

  • Select files by an absolute date or a relative date by using the /d parameter.

  • Build an archive tree of files by using variables such as @FSIZE and @FDATE.

  • Differentiate files from directories by using the @ISDIR variable.

  • Include special characters in the command line by using the hexadecimal code for the character, in 0xHH format (for example, 0x09 for a tab).

• This command works by implementing the recurse subdirectories flag on tools that are designed to process only a single file.

Examples

To list all of the batch files on drive C, type:

To list all of the directories on drive C, type:

To list all of the files in the current directory that are at least one year old, type:

To display the text file is outdated for each of the files in the current directory that are older than January 1, 2007, type:

To list the file name extensions of all the files in the current directory in column format, and add a tab before the extension, type:
