To undo pending changes, use the Unity Devops Version Control application or the CLI. For more flexibility and specificity with the way that you undo changes, use the CLI.

Undo changes in the GUI

You can undo changes in the Pending Changes tab of the UVCS desktop application:
  1. Select the files that you want to undo.
  2. Add a comment and select Undo.
  3. Select Undo.
If you select the arrow on the Undo button, you have two additional options:
  • Undo unchanged: this option removes any files that you have checked out but not changed. You can also use this option to remove unchanged files from the list of pending changes.
  • Undo checkouts keeping changes: this option allows you to remove the checkout on a file but keep the changes in your pending changes.

Undo changes in the CLI

Undo all changes in a workspace

You can delete all of your pending changes and start from your original workspace.
To remove your pending changes, use the 
cm undo -r
 command. The 
-r
executes the undo operation recursively.
cm undo -r

Filter the 
undo

By default, the 
undo
operation applies to all changes, but you can use filter options to restrict the undo to specific change types. In the following example, you have changed, added and deleted files:
>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size           Last Modified    PathChanged    49.23 KB       2 hours ago      code\bsp-renamed.cChanged    23.42 KB       2 hours ago      code\cgame\cg_drawtools.cChanged    61.23 KB       9 minutes ago    libs\cmdlib.hChanged      398 bytes    8 minutes ago    libs\str.hDeletedStatus     Size       PathRemoved    12.41 KB   code\bsp-temp.cAddedStatus    Size       Last Modified     PathAdded     4.42 KB    17 seconds ago    code\bsp-experimental.c
You can use the following filters to undo the addition and deletion of files but keep the changes in the modified files:
 >cm undo --added --deleted -r c:\Users\pablo\wkspaces\quake_path\code\bsp-experimental.c unchecked out correctly c:\Users\pablo\wkspaces\quake_path\code\bsp-temp.c unchecked out correctly
The filtered undo leaves you with the following status:
>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size           Last Modified     PathChanged    49.23 KB        2 hours ago      code\bsp-renamed.cChanged    23.42 KB        2 hours ago      code\cgame\cg_drawtools.cChanged    61.23 KB       10 minutes ago    libs\cmdlib.hChanged      398 bytes     9 minutes ago    libs\str.h

Undo a single change

To undo a single change, you run the 
undo
command and specify the path.
Note
To view your changes and their paths, run the 
cm status
command.
For example, you might have the following changes:
>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size         Last Modified    PathChanged    15.83 KB     50 seconds ago   code\cgame\cg_ents.cChanged    35.27 KB     30 seconds ago   code\cgame\cg_main.c
To undo only the changes to 
cg_main.c
, run the following command:
>cm undo code\cgame\cg_main.cc:\Users\pablo\wkspaces\quake_path\code\cgame\cg_main.c unchecked out correctly>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size         Last Modified    PathChanged    15.83 KB     50 seconds ago   code\cgame\cg_ents.c

Undo changes on specific paths

To undo changes only under a specific path, use the 
cm undo
command and specify the path.
For example, if you have the following changes in your workspace:
>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size         Last Modified    PathChanged    15.83 KB     50 seconds ago   code\lib\be_aas_cluster.cChanged    35.27 KB     5 minutes ago    code\cgame\cg_ents.cChanged    73.15 KB     5 minutes ago    code\cgame\cg_localents.cChanged    62.62 KB     5 minutes ago    code\renderer\tr_cmds.cChanged    12.26 KB     5 minutes ago    merge\Socket.cs
The following command undoes the changes in the 
code
folder but keeps the changes in the 
merge
folder:
>cm unco code -rc:\Users\pablo\wkspaces\quake_path\code\renderer\tr_cmds.c unchecked out correctlyc:\Users\pablo\wkspaces\quake_path\code\cgame\cg_localents.c unchecked out correctlyc:\Users\pablo\wkspaces\quake_path\code\cgame\cg_ents.c unchecked out correctlyc:\Users\pablo\wkspaces\quake_path\code\lib\be_aas_cluster.c unchecked out correctly>cm status/main/fix-1342@quake@localhost:8084 (cs:575 - head)ChangedStatus     Size         Last Modified    PathChanged    12.26 KB     5 minutes ago    merge\Socket.cs
Note
To filter more precisely, you can also use wildcards. For more information, refer to the CLI reference undo examples.
