Variable: lock-file-name-transforms

lock-file-name-transforms is a customizable variable defined in files.el.gz.

Value

nil

Documentation

Transforms to apply to buffer file name before making a lock file name.

This has the same syntax as auto-save-file-name-transforms, but applies to lock file names instead of auto-save file names.

By default, Emacs puts each lock file into the same directory as the file it locks, prepending ".#" to the base file name.

Note that changing this could break lock file functionality, e.g.: if different users access the same file, using different lock file settings; if accessing files on a shared file system from different hosts, using a transform that puts the lock files on a local file system.

This variable was added, or its default value changed, in Emacs 28.1.

Probably introduced at or before Emacs version 28.1.
