Difference between p4diff and p4diff2

Question

P4 diff和P4 diff2有什么区别？

Answer 1

p4 diff is used on the client, eg to compare a locally modified file to the version on the depot. p4 diff2 is used to compare two files on the server .

From the manual:

$ p4 help diff

On the client machine, diff a client file against the corresponding
revision in the depot. The file is compared only if the file is
opened for edit or a revision is provided. See 'p4 help revisions'
for details about specifying revisions.

$ p4 help diff2

'p4 diff2' runs on the server to compare one set of depot files (the
'source') to another (the 'target').  Source and target file sets
can be specified on the 'p4 diff2' command line or through a branch
view.
