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. -
Expression Definition FS.COMMAND Qualifier. Operates on a File System Command
Expression Definition FS.COMMAND Qualifier. Operates on a file system command. The user can issue multiple commands on a file transfer portal. (For example, ls to list files or mkdir to create a directory). This expression returns the current action that the user is taking. Possible values: Neighbor, login, ls, get, put, rename, mkdir, rmdir, del, logout, any. Following is an example: Add authorization policy pol1 “fs.command eq login && (fs.user eq administrator || fs.serverip eq 10.102.88.221 –netmask 255.255.255.252)” allow FS.USER Returns the user who is logged on to the file system. FS.SERVER Returns the host name of the target server. In the following example, the string win2k3-88-22 is the server name: fs.server eq win2k3-88-221 FS.SERVERIP Returns the IP address of the target server. FS.SERVICE Returns a shared root directory on the file server. If a particular folder is exposed as shared, a user can directly log on to the specified first level folder. This first level folder is called a service. For example, in the path \\hostname\SERVICEX\ETC, SERVICEX is the service. As another example, if a user accesses the file \\hostname\service1\dir1\file1.doc, FS.SERVICE will return service1. Following is an example: fs.service notcontains New FS.DOMAIN Returns the domain name of the target server. FS.PATH Returns the complete path of the file being accessed. For example, if a user accesses the file \\hostname\service1\dir1\file1.doc, FS.PATHwill return \service\dir1\file1.doc. Following is an example: fs.path notcontains SSL Expression Definition FS.FILE Returns the name of the file being accessed. -

Programming Project #2 Due: Thursday, May 13Th, 2004, 11:59 Pm
CS155: Computer Security Spring 2004 Programming Project #2 Due: Thursday, May 13th, 2004, 11:59 pm 1 Introduction 1.1 Summary In this project, you will write Josh, the journaling operator shell. Josh is a setuid-root shell that allows users to undertake a subset of root’s capabilities. Your starting point is OSH, a minimal shell developed by Gunnar Ritter. You may work alone, or in pairs. You should not collaborate with others outside your group. You will use the Boxes system again. Remember to test your Josh in a closedbox. This as- signment specification is quite long, but much of it is intended to clarify points of confusion raised by previous years’ students. Please be sure to read it carefully before beginning to code. 1.2 The Problem As discussed in class, the classical Unix permissions model does not manage privilege delegation effectively. To perform routine administrative tasks (such as cleaning out the /tmp directory), one must possess the root password, and can therefore perform other, undesirable actions (such as reading users’ mail). This limitation manifests itself most acutely in large Unix installations, where there are typically many administrators tasked with various duties. Finer granularity of access is required for such systems, along with the ability to correctly log the important events for post-attack analysis. Various systems have been devised to overcome this limitation, and allow unprivileged users to un- dertake some subset of root’s capabilities. A commonly-used example is Sudo (http://www.sudo.ws/). We will take an approach more like that taken by OSH, the Operator Shell by Michael Neuman. -

Yes, SAS Can Do! Manage External Files with SAS Programming
Yes, SAS® Can Do! --- Manage External Files With SAS Programming (Paper 3262 - 2015) Justin Jia, TransUnion Canada Amanda Lin, CIBC, Canada April 26-29, 2015 Dallas, Texas, USA Overview . Introduction . I. System Statements and Shell Commands X command and statement / %Sysexec macro statement/ Systask command . II. SAS Piping Functionality . III. SAS Call System Routine and System Function . IV. New SAS File Management Functions DCREATE function/ RENAME function/ FDELETE function/DLCREATEDIR option . V. Application Examples . Conclusion 2 Introduction . A good file management system is important for efficient documentation and project management. It would be beneficial to automate and standardize repetitive routine tasks via SAS programming: create, rename, move, copy, delete. Proc DATASETS, though powerful, is only effective for managing SAS files. How can we manage non-SAS external files or directories? 3 I. System Statements and Shell Commands . X <'command '> ; X " mkdir "&path.\ WLMU 999" "; . %Sysexec macro statement %sysexec mkdir "&path.\WLMU 999" ; . Systask statement systask command %unquote(%str(%') mkdir "&path.\WLMU 999" %str(%')); 4 Pros / Cons of System Statements/Commands . Advantages Not easy to monitor the execution status of submitted commands They use simple and easy DOS or (no return code). Unix commands. They cannot perform conditional Able to perform all kinds of file management tasks (create, execution since they are global. rename, copy, move, delete). data _null_; They are global commands and Action= 0; can exist anywhere in a SAS if Action=1 then do; program. X "mkdir "&path.\Try“ " ; . Disadvantages end; run; The X command will be executed every They prompt annoying flashing DOS window. time and the new directory Try will be created regardless of the value of Action.
