send control c on bash script to continue the loop process - bash

Question

I have a bash script that reads 10 lines on a file, each line has the server name that I need to boot up, the boot process takes long and outputs a lot of information, I need to send a "control c" on the script so it can proceed on the next server, or else the loop process will take long on each server during boot process
here is the actual output screen during boot process, it takes more than 30 minutes to complete on each server, loop may continue if control c is sent to the script/automation
$ eb restore environment_id
INFO: restoreEnvironment is starting.

Have you tried putting the eb restore command in the background with &?
I took a stab a rewriting what you posted. I don't know if it will work due to a few uncertainties (ie what do the contents of server.txt look like, do you copy it into the restore-all directory every time, do you put beanstalk/*/dev/.e* into restore-all each time, etc... etc...), but here it is:
#!/bin/bash
restore-all_dir=/jenkins/workspace/restore-all
InstanceIDs=/jenkins/workspace/environment-ids
EBFile=${restore-all_dir}/server.txt
echo -ne " PROCEEDING TO ${restore-all_dir} ..."
cd ${restore-all_dir}
echo -e "\b\b\b - done\n"
pwd
echo -ne " CREATING FOLDER ${restore-all_dir}/code ..."
mkdir ${restore-all_dir}/code
echo -e "\b\b\b - done\n"
pwd
ls -ltrh ${restore-all_dir}/code
for i in `awk '!/0/ {print $NF}' ${EBFile}`; do
echo "#########################################"
echo -e "#### RESTORING: ${i}\n"
echo -en " COPYING BEANSTALKFILES ..."
mkdir ${restore-all_dir}/code/${i}
cd ${restore-all_dir}/code/${i}
cp -pr ${restore-all_dir}/beanstalk/${i}/dev/.e* ${restore-all_dir}/code/${i}
echo -e "\b\b\b - done\n"
echo -en " TRIGGERING EB RESTORE ..."
cd ${restore-all_dir}/code/${i}
echo "eb restore `tail -1 ${InstanceIDs}/${i}-dev.txt` > ${restore-all_dir}/${i}_output.out &" ## directs output to a file and puts the process into the background
echo -e "\b\b\b - put into background\n output saved in ${restore-all_dir}/${i}_output.out\n"
## Is this necessary in every iteration, or can it be excluded and just removed with the final rm -rf command?
## echo -en " REMOVE CODE FOLDER ..."
## cd ${restore-all_dir}/code
## rm -rf ${restore-all_dir}/code/*
## echo -e "\b\b\b - done\n"
done
## this will loop "working..." until all background eb restore jobs are no longer "Running"
echo -en "\n working..."
while `jobs | awk '/Running/ && /eb restore/ {count++} END{if (count>=1) print "true"; else print "false"}'`; do
echo -en "\b\b\b\b\b\b\b\b\b\b\b working..."
done
echo -e "\b\b\b\b\b\b\b\b\b\b\b - done \n"
## this will also remove the output files unless they are put somewhere else
echo -en " REMOVE WORKSPACE FOLDER ..."
rm -rf ${restore-all_dir}/*
echo -e "\b\b\b - done\n"
