i have this bash script code and i want to run the read command side by side with the while loop as the read command fetch data from user and save it in some file and the while loop do checking on a related something , so any suggestions like doing them in both terminals or something like that

Thanks

 #!/bin/bash 
 trap "echo "" > /home/........./file.txt" SIGINT SIGTERM SIGHUP
 while sleep 2
do
read -s -n 1 key 
 if [[ $key = "" ]]; then 
 echo >> somefile
 else
 echo "You pressed '$key'"
 fi
clear
done
 while sleep $sleepInterval
 do
 i=0
 while read line
 do
 somecommands
 done

This is how I do that:

#!/bin/bash

a=0

function ACTION ()

if [[ "$bb" == "Q" 

while true; do
 read -t 1 -n 1 bb && ACTION
 echo -ne "Hello $a times. Hit "q" to quit."'r' 
 a=`echo "$a + 1" | bc`
done
exit 0

And this is what was answered at Stackoverflow by Andy and works great here.

The script is his (I just added the trap part as he says that terminal would be in a weird state if the script gets killed):

#!/bin/bash

trap 'echo -e "nn############n# #n# Bye bye #n# #n############n" && exit 1' INT 
trap 'notify-send "Bye bye" "The terminal has been closed" && exit 1' HUP

if [ ! -t 0 ]; then
 echo "This script must be run from a terminal"
 exit 1
fi

stty -echo -icanon time 0 min 0

count=0
keypress=''
while true; do
 let count+=1
 echo -ne $count'r'

 # This stuff goes in _handle_keys
 read keypress
 case $keypress in
 # This case is for no keypress
 "")
 ;;
 $'e[C')
 echo "derecha"
 ;;
 $'e[D')
 echo "izquierda"
 ;;
 # If you want to do something for unknown keys, otherwise leave this out
 *)
 echo "unknown input $keypress"
 ;;
 esac
 # End _handle_keys
done

stty sane

i would make the inf. loop its own separate script then when i run it put a ampersand after it

#!/bin/bash
cat /var/log/dmesg
~/inf-loop.sh &
ls /var/cache/apt/archive/*.deb
