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 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 determined. 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 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.
