I'd like to know if there is any way to determine a terminal's background color ?

In my case, using gnome-terminal. It might matter, since it's entirety up to the terminal application to draw the background of its windows, which may even be something else than a plain color.

I've came up with the following:

#!/bin/sh
#
# Query a property from the terminal, e.g. background color.
#
# XTerm Operating System Commands
#     "ESC ] Ps;Pt ST"

oldstty=$(stty -g)

# What to query?
# 11: text background
Ps=${1:-11}

stty raw -echo min 0 time 0
# stty raw -echo min 0 time 1
printf "\033]$Ps;?\033\\"
# xterm needs the sleep (or "time 1", but that is 1/10th second).
sleep 0.00000001
read -r answer
# echo $answer | cat -A
result=${answer#*;}
stty $oldstty
# Remove escape at the end.
echo $result | sed 's/[^rgb:0-9a-f/]\+$//'

DCF Terminal Value Formula, DCF Terminal value formula is used to calculate the value a business beyond the forecast period in DCF analysis. It's a major part of a financial model. The formula for calculating the perpetual growth terminal value is: TV = (FCFn x (1 + g)) / (WACC – g)

There's an xterm control sequence for this:

\e]11;?\a

(\e and \a are the ESC and BEL characters, respectively.)

Xterm-compatible terminals should reply with the same sequence, with the question mark replaced by an X11 colorspec, e.g. rgb:0000/0000/0000 for black.

How to Calculate Terminal Value in a DCF Analysis, Table of Contents: Terminal Value = Unlevered FCF in Year 1 of Terminal Period / (WACC – Terminal UFCF Growth Rate) Terminal Value = Final Year UFCF * (1 + Terminal UFCF Growth Rate) / (WACC – Terminal UFCF Growth Rate) There are 4 essential steps that you need to follow to estimate a company's terminal value: Find all required financial data Implement the discounted free cash flow (DCF) analysis Calculate the company's perpetuity value (PV)

Aside from apparently rxvt-only $COLORFGBG, I am not aware that anything else even exists. Mostly people seem to be referring to how vim does it, and even that is an educated guess at best.

Terminal Value, The terminal value is typically calculated by applying an appropriate multiple (EV/EBITDA, EV/EBIT, etc.) to the relevant statistic projected for the last projected year. Since the DCF values cash flow available to all providers of capital, EV multiples are generally used rather than equity value multiples. Terminal value is the worth of a company at a point in the future, for example, five years from now. The simplest terminal value formula is to calculate the future value of a metric such as earnings and multiply that to get terminal value. The multiplier varies according to the industry the company is in. Learn the Terminal Value Definition

The multiple EBITDA approach measures the firm value of the enterprise – that is, the� How to Calculate Terminal Velocity Method 1 of 3: Solving for Terminal Velocity. Use the terminal velocity formula, v = the square root of ( (2*m*g)/ Method 2 of 3: Find the Gravitational Force. Find the mass of the falling object. This should be measured in grams or Method 3 of 3: Determine

Do you mean a method to ascertain the terminal background colour, or set the terminal colour?

If the latter you could query your terminal's PS1 environment variable to obtain the colour.

There's an article on setting (and so deriving) the terminal colours here: http://www.ibm.com/developerworks/linux/library/l-tip-prompt/

Terminal Value Formula, Guide to Terminal Value Formula. Here we discuss how to calculate the terminal value using Perpetuity growth & Exit multiple method with examples. When choosing a wiring terminal, you need to remember that there is a correct size for every wire gauge and a correct crimping die to match. Insulated terminals are selected by a range of sizes noted by the color of the insulation. Any wire larger than 10-gauge requires a non-insulated terminal.

How to Determine the Terminal Value of Commercial Real Estate, For these reasons, an alternative approach is often used. Calculate the terminal value by assuming a constant cash flow growth rate into perpetuity, starting in the � Solution: Calculation of terminal cash flow will be –. After-Tax Proceeds from Disposal of Machine = Actual Proceed Received from Disposal – Tax on Disposal. Tax on Disposal = (Proceeds Received on Disposal – Book Value on Disposal) * Tax Rate. Actual Proceeds Received on Disposal = $25,000.

Terminal Value in DCF, There are different ways to find out the terminal value of cash flows. Most popularly used is the Gordon Growth Model where a company is valued as Perpetuity. The terminal growth rate is a constant rate at which a firm’s expected free cash flows are assumed to grow at, indefinitely. This growth rate is used beyond the forecast period in a discounted cash flow (DCF) model, from the end of forecasting period until and assume that the firm’s free cash flow will continue

Terminal value (finance), To determine the present value of the terminal value, one must discount its value at T0 by a factor equal to the number of years included in the initial projection� The cathode (positive) terminal of the cell is connected to a lead oxide plate, while the anode (negative) terminal is connected to a lead plate. Both plates are immersed in sulfuric acid, the electrolyte for the system. Figure 3. Artist’s conception of a lead-acid cell.

  • This doesn't seem to work with gnome-terminal 3.6.2.
  • Some information on how to utilize this would be an excellent addition. (For instance, a snippet of shell-script that prints a word in a different foreground colour depending on the shell's background colour?)
  • (Also, I suspect this will only obtain the background colour for the text, if one is shut. Not the background-colour of the actual terminal window, which I suspect is still unobtainable outside of rxvt.)
  • In Mac 10.10.4, this (and @blueyed's similar answer) doesn't seem to work in Apple Terminal (which identifies itself as xterm-color), but does work in regular xterm.
  • On my system (Ubuntu 15.10), this works with xterm and GNOME Terminal 3.16.2, but not with MATE Terminal 1.10.1.
  • @ELLIOTTCABLE This definitely gets the background of the terminal window. It's in the linked page: "Ps = 1 1 -> Change VT100 text background color to Pt." and "For colors and font, if Pt is a "?", the control sequence elicits a response which consists of the control sequence which would set the corresponding value."
  • I mean to ascertain the background color. Not the color used to print characters (using escape codes), but the of window itself. Nice article however :)
