p4 lock

Synopsis

Lock an opened file against changelist submission.

Syntax

p4 [g-opts] lock [-c changelist#] [file ...]

Description

Locking files prevents all other users from submitting changes to those files. If the files are already locked by another user, p4 lock fails. When the user who locked a particular file submits the file, the lock is released.

This command is normally called with a specific file argument; if no file argument is provided, all open files in the default changelist are locked. If the -c changelist# flag is used, all open files matching the given file pattern in changelist changelist# are locked.

Options

-c changelist#	Lock only files included in changelist changelist#
g-opts	See the Global Options section.
