I'm trying to learn bash scripting and I would like to write a script that outputs the top processes every two seconds, such as

while [ 1 ]; do
 # echo "$(top -b -o +%MEM | head -n 15)" # for testing
 echo "$(top -b -o +%MEM | head -n 15)" >> /test_unix.txt 
 echo "***********************************************" >> /test_unix.txt
 printf "n" >> /test_unix.txt
 sleep 2
done

When I run this script normally I get (among others) the following output:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 5299 root 20 0 6436592 5.164g 19352 S 106.2 33.0 2:45.67 /very/long/path/to/bin/node --expose-gc --max_old_space_size=8000 /another/very/long/path/node_m+

So we see that the string ends with a plus (+) sign (i.e., path/node_m+) instead of displaying the full command. The strange thing is when I zoom out (enough) on my Ubuntu terminal (Ctrl+-), and then run the script, it will append the full string as such

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 5299 root 20 0 6436592 5.164g 19352 S 106.2 33.0 2:45.67 /very/long/path/to/bin/node --expose-gc --max_old_space_size=8000 /another/very/long/path/node_modules/more/path/index.js /path/.nvm/versions/node/

How can I ensure that the script will always output the full string, even when the terminal is not "zoomed out"?
