sync -- Synchronize the client with its view of the depot
p4 sync [ -f -n ] [ file[revRange] ... ]
Sync updates the client workspace to reflect its current view (if
it has changed) and the current contents of the depot (if it has
changed). The client view is used to map client file names to
depot file names and vice versa.
Sync adds files that are in the client view but which have not been
retrieved before. Sync deletes previously retrieved files which
are no longer in the client view or have been deleted from the
depot. Sync updates files which are still in the client view and
which have been updated in the depot.
Normally, sync affects all files in the client workspace. If file
arguments are given, sync limits its operation to those files.
The file arguments may contain wildcards.
If the file argument includes a revision specifier, then the given
revision is retrieved. Normally, the head revision is retrieved.
See 'p4 help revisions' for help specifying revisions.
If the file argument includes a revision range specification, then
only files selected by the revision range are updated, and the
highest revision in the range is used.
Normally, sync will not clobber files in the client workspace that
the user has made writable. Setting the 'clobber' option in the
client spec disables this safety check.
The -f flag forces resynchronization even if the client already
has the file, and clobbers writable files. This flag doesn't affect
open files.
The -n flag causes sync not to update the client workspace, but to
display what normally would be updated.
