Terminal command to show a summary of memory used, temperature, and GPU use in a single screen, in a simple way

Question

Is there a Terminal command to show a summary of memory used, temperature degrees, and GPU use in a single screen, in a simple way?
I want in terminal to give me information in a summary fashion of Memory used (not swap etc.), GPU Use (as a percentage), and temperature degrees - how hot is getting CPU?
Right now, I must use three different terminal commands:
watch free -m    # For Memory use
watch sensors    # For Temperature
watch ndivia-smi # For GPU use

Is there a way to display such information in a single screen?
These commands produce a lot of information that someone may not need it rightaway.
The first line may show the memory use.
The second line may show GPU use.
The third line may display Temperatures.
I want from free -m "available". I want from nvidia-smi "Volatile GPU-Util" and from sensors all the temperatures in percentage without showing their limits (from that to that), for example
Available memory    5500000

Volatile GPU-Util  20%

CPUtemp1           40oC
Fantemp1           41oC
FanTemp2           42oC
etc...

Is that possible?
Sample outputs:
free -m output
$ free -m

Swap:          2047          57        1990

You can easily extract the specific parts of interest from the long outputs by using various command-line utilities, e.g. awk.

You're interested in showing only the 'available' memory from the output of free -m. Note that this number appears as the 7th string in the 2nd line of the output of free -m. So you can use the following command to extract this number

free -m | awk '{if (NR == 2) {print $7}}'

To "watch" the output, you can use the following

watch 'free -m | awk '''{if (NR == 2) {print $7}}''

Similarly, it seems you want to extract the 2nd string from the 9th line from the output of the nvidia-smi command (32% as per the output you added to the question). So you can extract this value by the following command

nvidia-smi | awk '{if (NR == 9) {print $2}}'

and watch it using

watch 'nvidia-smi | awk '''{if (NR == 9) {print $2}}''

From the output of sensors I believe you're trying to extract the 2nd string from line numbers 15 to 20 (which report temp1 to temp6). So you can use

sensors | awk '{if (NR>=15&&NR<=20) {print $2}}'

and to watch

watch 'sensors | awk '''{if (NR>=15&&NR<=20) {print $2}}''

To watch all three at the same time, you can use the following command

watch 'free -m | awk '''{if (NR == 2) {print $7}}'''; nvidia-smi | awk '''{if (NR == 9) {print $2}}'''; sensors | awk '''{if (NR>=15&&NR<=20) {print $2}}''
