    \$\begingroup\$ The good old exec trick will do better: ls>l;exec $0. Shorter, but boring. \$\endgroup\$ Commented Apr 1, 2016 at 14:46

    \$\begingroup\$ Even though you delete y, yes will still continue to write to the same file handle that it had. Run lsof | grep yes and you should see something like /path/to/y (deleted). This will fill up the disk and fail. \$\endgroup\$ Commented Apr 2, 2016 at 8:43

    \$\begingroup\$ Instead of rm y you can use >y which will truncate the existing file. It is also a bit shorter. \$\endgroup\$ Commented Apr 2, 2016 at 21:47
