I really appreciate you help me!

I don’t have much real knowledge of this kind of stuff, nor know the technical terms. Most of what I know is just from messing around, one of these days I should actually read a book.

By “call” I mean be able to input a function? into another line. So if these are the right terms.
variable=function
math= (2+1)/2
answer=math
but be able to do that with the command I have, with the output being assigned a variable

Yeah I realized that the command was pretty messy but it was the only way I could figure it out. The original output is
Code:
eth0:UP (in=0.0Mbps/out=0.0Mbps):1 UP: OK

the issue I had was that the numbers scale? Up . for example in=5.0, in=10.4, in=28.3. This was the only way I could figure out how to get the numbers regardless if it was three or two digits.

The main purpose of the program is to write the percentage to an usb device. I figure if I could get as far as printf the percentage, the next step would be easy. Anyways the writing to usb command is just
Code:
writeUSB(perf_fs_usb,downspeed,upspeed)

vconsole.conf

VCONSOLE.CONF(5)						   vconsole.conf						  VCONSOLE.CONF(5)

NAME

       vconsole.conf - configuration file for the virtual console

SYNOPSIS

       /etc/vconsole.conf

DESCRIPTION

       The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.

       The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
       possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
       allowing applications to read the file without implementing a shell compatible execution engine.

       Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
       vconsole.font.unimap= may be used to override the console settings at boot.

       Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
       as fallback.

OPTIONS

       The following options are understood:

       KEYMAP=, KEYMAP_TOGGLE=
	   Configures the key mapping table of for they keyboard.  KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
	   a second toggle keymap and is by default unset.

       FONT=, FONT_MAP=, FONT_UNIMAP=
	   Configures the console font, the console map and the unicode font map.  FONT= defaults to latarcyrheb-sun16.

EXAMPLE

       Example 1. German keyboard and console

       /etc/vconsole.conf:

	   KEYMAP=de-latin1
	   FONT=latarcyrheb-sun16
