speedometer - measure and display the rate of data across a network connection
SYNOPSIS
speedometer [options] tap [[-c] tap] ...
DESCRIPTION
Monitor network traffic or speed/progress of a file transfer. At least one tap option (-f, -rx, -tx) must be entered. Option -c starts a
new column, otherwise taps are piled vertically.
Note: before you use the program, satrt generating traffic by transferring files in/out e.g. with scp(1) in the network you're measuring.
OPTIONS -b Use old blocky display instead of smoothed display even when UTF-8 encoding is detected.
-f filename [size]
Display download speed with progress bar. This option must be used if directly following another file tap without an expected size
specified.
-i interval
Interval in seconds. Examples: 5 or 0.25". Default is 1.
-p Use plain-text display (one tap only).
-rx iface
Display bytes received on network interface.
-tx iface
Display bytes transmitted on network interface.
-z Report zero size on files that don't exist instead of waiting for them to be created
EXAMPLES
How long it will take for my 38MB transfer to finish?
speedometer favorite_episode.rm $(( 38 * 1024 * 1024 ))
How quickly is another transfer going?
speedometer dl/big.avi
How fast is this LAN?
host-a$ cat /dev/zero | nc -l -p 12345
host-b$ nc host-a 12345 > /dev/null
host-b$ speedometer -rx eth0
How fast is the upstream on this ADSL line?
speedometer -tx ppp0
How fast can I write data to my filesystem? (with at least 1GB free)
dd bs=1000000 count=1000 if=/dev/zero of=bigfile &

colortest-python - Display color test chart and convert between color values
SYNOPSIS
colortest-python
DESCRIPTION
Displays 256, 88 and 16 color tables depending on what the terminal supports. Also provides for conversion between 256 and 88 color values.
The program automatically detects 8, 16, 88, 256 color capabilities (via ncurses) and displays the appropriate color charts. Program can
display the colors as blocks or 2d cubes optionally with color values overlaid in int or hex values, it can show the full rgb text string
and show the display with a vertical (default) or horizontal orientation.
In addition to the color charts it can also convert between 256 and 88 color values. This can be useful when converting various terminals
like between urxvt and xterm-256.
The goal of this program was to provide the functionality of all the various Perl and sh scripts in one place with some bells and whistles.

-c, --cube-slice
Display as cube slices (vs block).

-h, --help

-n, --numbers
Include color escape numbers on chart.
-l, --rgb
Long format. RGB values as text.
-p, --padding
