Unlock network files locked by Samba Linux / Unix Server
Samba is a free Linux/Unix software which provides file and print access for Microsoft Windows clients. If you have a Linux file server or Linux based NAS device on a network with Windows clients you are probably using Samba.
Samba deals with file locking, preventing file corruption and data loss when two or more clients try to simultaneously edit the same file. There may be situations where you need to force file unlock, for example when file was closed but lock was not properly released by Samba.
Unfortunately Samba doesn't allow unlocking individual files. There are couple of workarounds though.
