Compare a client workspace file to a revision in the depot
p4 diff runs a diff program on the Perforce client, comparing files in the client workspace to revisions in the depot. This command takes a file argument, which can contain a revision specifier. If a revision specifier is included, the client will be diffed against the specified revision. If a revision specifier is not included, the client workspace file will be compared against the revision currently being edited (usually the head revision). In either case, the client file must be open for edit, or the comparison must be against a revision other than the one the client file was last synced to.
If the file argument includes wildcards, all open files that match the file pattern will be diffed. If no file argument is provided, all open files will be diffed.
By default, the diff routine used is one provided with the Perforce client. You can change this diff routine to any other diff program by setting the P4DIFF environment or registry variable.
| -f | Force the diff, even when the client file is not open for edit. |
| -dflag | Pass flag flag to the underlying diff routine (please see the Examples below for more details) |
| -sa | Diff only open files that are different from the revision in the depot, or are missing. |
| -sd | Diff only files that are missing on the client. |
| -se | Diff only unopened files that are different from the revision on the client. |
| -sr | Diff only unopened files that are identical to the revision on the client. |
| g_opts | See global options section. |
