want file to regenerate after deletion
I looked into the sticky bit, but I think, if possible, that I would prefer to have the file recreate itself after deletion. The file is several directories deep, and from time to time the top level directory will be trashed. I need the file to recreate after this. Is it possible to perhaps create a symlink that, if the file is deleted, the source file will recreate it?

NAME
sticky - mark files for special treatment
DESCRIPTION
The sticky bit (file mode bit 01000, see chmod(2)) is used to indicate special treatment of certain files and directories. A directory for
which the sticky bit is set restricts deletion of files it contains. A file in a sticky directory can only be removed or renamed by a user
who has write permission on the directory, and either owns the file, owns the directory, has write permission on the file, or is a privi-
leged user. Setting the sticky bit is useful for directories such as /tmp, which must be publicly writable but should deny users permission
to arbitrarily delete or rename the files of others.
If the sticky bit is set on a regular file and no execute bits are set, the system's page cache will not be used to hold the file's data.
This bit is normally set on swap files of diskless clients so that accesses to these files do not flush more valuable data from the sys-
tem's cache. Moreover, by default such files are treated as swap files, whose inode modification times may not necessarily be correctly
recorded on permanent storage.
Any user may create a sticky directory. See chmod for details about modifying file modes.
SEE ALSO
chmod(1), chmod(2), chown(2), mkdir(2), rename(2), unlink(2)
BUGS
The mkdir(2) function will not create a directory with the sticky bit set.
