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 (Estimated 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 decrease, 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 Gigabytes(x*1024*1024*1024).

       -m, --maxblock max_block_size
              Sets the maximum 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 determined. Multiple occurrences of -f
              will read the files in the order they are specified on the cmdline, and sizes  will
              be  added  to each other. Note that this option remains for backward compatibility,
              it is far simpler to just specify the input files without 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 outputting/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.
