# Command Line Options

There are commands for performing Admin Tool tasks on-demand or on a scheduled basis. In addition there are unique commands for working with repositories and REQ files.

The majority of the command-line functions use a single executable, ReqAdmn.exe, that accepts the command-line parameters to determine which function to perform. In other cases a different executable may be used; for example, generating dynamic document previews uses the BuildDocPreviews executable (BuildDocPreviews.exe).

The command-line functions described in this section are as follows:

- Accessing the Command Prompt
- About Common Options
- exp_AdminBuildingRepository.html
- Loading a Repository
- Building an Authoring Database
- Data Dictionary Builder
- Preparing an REQ File for External Delivery
- Trimming a Repository to a Single Line of Business
- Updating Content References in Dynamic Documents
- Generating Dynamic Document Outlines
- Generating Dynamic Document Previews
- Database Connection Strings
- Removing Orphaned/Unused Rules
- PrepOPPSA: Creating Stores and Types for OPPSA
