Flags to configure the client behavior.
Leaves all files writable on the client; by default, only files opened by 'p4 edit' are writable. If set, files might be clobbered as a result of ignoring the clobber option (see below).
Permits 'p4 sync' to overwrite writable files on the client. noclobber is ignored if allwrite is set.
Compresses data sent between the client and server to speed up slow connections.
Allows only the client owner to use or change the client spec. Prevents the client spec from being deleted or unloaded.
Causes 'p4 sync' and 'p4 submit' to preserve file modification time, as with files with the +m type modifier. (See 'p4 help filetypes'.) With nomodtime, file timestamps are updated by sync and submit operations.
Makes 'p4 sync' attempt to delete a workspace directory when all files in it are removed.
