       These  tools  operate  on  object's  trashtime value, i.e. the number of seconds the file is preserved in
       special trash directory before it's finally removed from  filesystem.   Trashtime  must  be  non-negative
       integer value.

       mfsgettrashtime  prints  current  trashtime  value of given object(s).  -r option enables recursive mode,
       which works as usual for every given file, but for every  given  directory  additionally  prints  current
       trashtime value of all contained objects (files and directories).

       mfssettrashtime  changes  current  trashtime  value  of  given  object(s).   If new value is specified in
       SECONDS+ form, trashtime value is increased to  SECONDS  for  objects  with  lower  trashtime  value  and
       unchanged for the rest. Similarly, if new value is specified as SECONDS-, trashtime value is decreased to
       SECONDS  for  objects with higher trashtime value and unchanged for the rest. -r option enables recursive
       mode.  These tools can be used on any file, directory or deleted (trash) file.

       mfscopytrashtime tool can be used to copy trashtime value from one object to another.

       mfsrgettrashtime and mfsrsettrashtime are deprecated aliases for mfsgettrashtime-r  and  mfssettrashtime-r respectively.

       Most of mfstools use -n, -h, -H, -k, -m and -g options to select format of printed numbers. -n causes  to
       print  exact  numbers,  -h uses binary prefixes (Ki, Mi, Gi as 2^10, 2^20 etc.) while -H uses SI prefixes
       (k, M, G as 10^3, 10^6 etc.). -k, -m and -g show plain numbers  respectivaly  in  kibis  (binary  kilo  -
       1024),  mebis  (binary  mega  -  1024^2)  and  gibis (binary giga - 1024^3).  The same can be achieved by
       setting MFSHRFORMAT environment variable to: 0 (exact numbers), 1 or h (binary  prefixes),  2  or  H  (SI
       prefixes),  3  or  h+  (exact  numbers and binary prefixes), 4 or H+ (exact numbers and SI prefixes). The
       default is to print just exact numbers.

       When new object is created in MooseFS, attributes such as storage class, trashtime and  extra  attributes
       are  inherited  from  parent  directory.  So  if  you  set  i.e. "noowner" attribute and storage class to
       "important" in a directory then every new object created in this directory will have storage class set to
       "important" and "noowner" flag set. A newly created  object  inherits  always  the  current  set  of  its
       parent's  attributes.  Changing  a  directory  attribute does not affect its already created children. To
       change an attribute for a directory and all of its children use -r option.

       Since  version  3.0 of MooseFS trashtime is stored in the system as number of hours the file is preserved
       in trash directory. Given value in seconds is rounded up to hours.
