 -b : Set baseTime type as:

      c : file creation time

-R : If specified, recursively deletes expiration times for files contained in subdirectories.

-t  : set expiration time in the form YYYY-MM-DD or optionally,

      YYYY-MM-DD-hh:mm:ss, where:

        YYYY is the year

        MM is the month number (1-12)

        DD is the day number (1-31, depending on the month and leap year)

        hh is the hour (0-23)

        mm is the minute (0-59)

        ss is the second (0-59)

-v  : enable verbose listing mode

Usage Notes: 

  • if -b is not specified, "-b n” is assumed (base time is current time when command is issued)
  • h, -m, -s, -d and -y may be combined to specify base time + years/days/hours/minutes/seconds
  • -c and -t may not be combined with any other options
  • HPSS administrators may disable the file expiration feature, and may also restrict the use of this command.


1. Set expiration time for all files that match the pattern “*.c” to their creation time + 2 years, 2 months and 8 days:
