NAME
       pipemeter - measure speed of data going through a pipe/redirection

SYNOPSIS
       pipemeter  [ -alV ] [ -s	size ] [ -b block_size ] [ -m max_block_size ]
       [ -i interval ] [ -f infile -f infile2 ]	infile infile2 ...

DESCRIPTION
       pipemeter simply	takes input on stdin, and redirects it to its  stdout.
       While  doing  this, it measures how fast	the data is moving through it.
       Alternatively, with the -s parameter, shows a progress bar as  data  is
       piped  through  it.   All  output  generated by pipemeter is written to
       stderr.

       While running in	progress mode, pipemeter will display the  ETA	(Esti-
       mated Time of Arrival). When exiting, it	will change this field to show
       the elapsed time	for the	program. In rate-only mode, it will just  show
       elapsed time.

       Note  that  as of pipemeter 0.8,	Adaptive Block Sizing is used to speed
       up the movement of data through it. It will increase, or	sometimes  de-
       crease,	the  block  size in an attempt to find the one that works best
       for the combination of input and	output.	This also helps	it deal	better
       with,  for instance, a temporarily busy disk. You can use -a to turn it
       off.

       -s, --size size
	      Sets the size of the input, and turns on the progress bar.

       -b, --blocksize block_size
	      Sets the size of blocks, in bytes, to move through  the  program
	      at  once.	Default	is 8192. A suffix of K means Kilobytes(x*1024)
	      means    Megabytes(x*1024*1024),	  and	 G     means	 Giga-
	      bytes(x*1024*1024*1024).

       -m, --maxblock max_block_size
	      Sets the maxium block size for adaptive block sizing. Default is
	      8M.

       -i, --interval interval
	      Specify the number of  seconds  between  updates	on  the	 speed
	      and/or progress bar.

       -f, --file infile
	      infile  specifies	 a  file  to be	read instead of	stdin. It will
	      also automatically turn on the progress bar if a size can	be de-
	      termined.	 Multiple  occurances of -f will read the files	in the
	      order they are specified on the cmdline, and sizes will be added
	      to eachother. Note that this option remains for backward compat-
	      ibility, it is far simpler to just specify the input files with-
	      out options.

       -F, --list listfile
	      specifies	 a  file to read in the	list of	input files from. Each
	      line is a	path to	a file,	terminated by a	newline.

       -r, --report
	      report only mode.	This  causes  the  program  to	suppress  out-
	      putting/calculating  while  running.  It will print out only one
	      line.

       -a, --autooff
	      turn off adaptive	block sizing. Sometimes	 ABS  can  use	insane
	      amounts of RAM, such as when reading and writing to RAM disks.

       -V, --version
	      Prints a version number and exits.

       -l, --log
	      Turns on logging mode. Uses only newlines, no returns.
