The Team Foundation Version Control (TFVC) undelete command restores items that were previously deleted.

Note

The results of this command aren't visible in other workspaces until you perform a check-in operation. For more information, see Develop code and manage pending changes.

Prerequisites

To use the undelete command:

  • You must have the Check out permission set to Allow.
  • If you include the /lock option with a value other than None, you must have the Lock permission set to Allow.
  • You must own the workspace or have the global Administer workspaces permission set to Allow.

For more information, see Default TFVC permissions.

Syntax

tf undelete [/noget] [/lock:(none|checkin|checkout)] 
[/recursive] <item-specification>[;<deletion-ID>] [/login:<username>,[<password>]]

Parameters

The following sections describe arguments and options of the undelete command.

Arguments

Argument Description
<item-specification> Identifies the file or folder to restore. For more information about how TFVC parses <item-specification> values to determine which items are within scope, see Use Team Foundation version control commands.
<deletion-ID> Specifies a unique identifier that disambiguates multiple deleted items that have the same name.
<username> Provides a value to the /login option. You can specify this value as either DOMAIN\<username> or <username>.

Options

Option

Description

/noget

Restores the deleted item to your workspace. Pending completion of a check-in operation, this option then restores the item on the server but doesn't immediately retrieve a physical copy of the item to disk.

/lock

Prevents other users from checking in or checking out the specified files. For more information, see Understand lock types.

Lock options:

  • None: This option is the default value. No lock is applied.
  • Checkin: Other users can check out the specified items but they can't check in revisions to locked files until you release the lock by checking in the locked files. If any other users have locked any of the specified items, the lock operation fails.
  • Checkout: This option prevents other users from checking in or checking out any of the specified items until you release the lock by checking in the locked files. If any other users have locked any of the specified items, the lock operation fails.

/recursive

Restores all files and subfolders from the specified directory.

/login

Specifies the username and password to authenticate the user with Azure DevOps.

Remarks

The undelete command of the tf command-line feature schedules specified files or folders for restoration pending the completion of a check-in operation. It also retrieves the specified items from the server to the local disk unless you explicitly include the /noget option.

When files or folders that have the same name have been deleted from the same server folder, you must include a value for the <deletion-ID> parameter to indicate which of the deleted items you want to restore. You can obtain a <deletion-ID> by using the dir command.

If you want to change a file after restoring it, check out the file for editing by using the checkout command as usual.

When your <item-specification> value specifies a folder, TFVC restores by default all the folder's files and subfolders and the files that they contain. If you don't want to restore all the items in a folder, you must first undelete the folder and its items and then delete the items that you don't want to keep.

For more information about how to use the tf command-line utility, see Use Team Foundation version control commands.

Examples

The following example restores 314.cs to the server folder that 314.cs was deleted from. The command also retrieves a read-only copy of the latest version in the current workspace.

C:\projects>tf undelete c:\math\314.cs

The following example displays deletion IDs for all items on the server that have been deleted more than one time:

c:\projects>tf dir $/ /deleted

Output from the previous command might look like the following sample:

$/projects/math/314.cs;X10
$/projects/math/314.cs;X11

The following example restores the X11 version of 314.cs to the server folder that the file was deleted from. The command also retrieves a read-only copy of the latest version in the current workspace.

c:\projects>tf undelete 314.cs;X11
