delay — a constant delay generator

       Romain Vimont <rom@rom1v.com>

delay  introduces  a constant delay between its standard input and its standard output. The data from its
       stdin will be stored until it has been written to stdout. The required delay argument specifies the delay
       time in millisecond.

       delay supports the following options:

       delay
               delay is the desired delay time, in milliseconds. The following modifiers are accepted:
               12s means 12 seconds
               12m means 12 minutes
               12h means 12 hours

       -bbufsize
               buffer size stores the data until it  has  been  written  to  stdout,  in  bytes.  The  following
       modifiers are accepted:
               12k means 12Kb
               12m means 12Mb
               12g means 12Gb

       delay the output of command_A to command_B by 5 seconds:
               $ command_A | delay 5s | command_B

       delay the output of command_A to command_B by 5 seconds with 10MB buffer:
               $ command_A | delay -b 10m 5s | command_B
