into - copy into a file without destroying it
Into copies its standard input into the specified outfile, but
doesn't actually modify the file until it gets EOF. This is useful in a
pipeline for putting stuff back in the "same place." The
outfile is not overwritten if that would make it zero length, unless
the -f option is given. That option also forces overwriting of the
outfile even if it is not directly writable (as long as the directory
is writable).
For efficiency reasons, the directory containing the outfile must be
writable by the invoker.
The original outfile's owner is not preserved.
