Command-Line Exit Codes
The Team Foundation source control command-line utility tf provides exit codes that indicate the level of success for a command.
The following command-line exit codes are defined for tf.exe.
Partial success; this means at least something, or possibly everything, failed to succeed.
In order to check out two files, you might type the following command at the command-line:
tf checkout foo.cs bar.cs
If one of the files you are trying to check out does not exist on the server, you are returned 1 for partial success.
