NAME
undelete - attempt to recover a deleted fileLIBRARY
Lb libcSYNOPSIS
In unistd.h Ft int Fn undelete const char *pathDESCRIPTION
The Fn undelete system call attempts to recover the deleted file named by Fa path . Currently, this works only when the named object is a whiteout in a union file system. The system call removes the whiteout causing any objects in a lower layer of the union stack to become visible once more.Eventually, the Fn undelete functionality may be expanded to other file systems able to recover deleted files such as the log-structured file system.
