Thanks everyone, but I was looking for something easier. With some more dragging around I found the best way to do it without too much complexity.
Adding the code below for reference.
Code:
#!/bin/bash
FILE2=/usr/local/app/command_file.log
while read line; do
command=$(echo $line)
log=$(echo $line | awk -F'"' '{$0=$2}1')
count=$(ps aux | grep -i "tscV6Connector" | grep -v "grep" | wc -l)
instance=$(echo $line | awk -F'"' '{$0=$4}1')
if [ $count -le 6 ];
then
echo "Running command for "$log" with name starting with "$instance"...."
nohup "additional_command_parameters" > /usr/local/app/log/"$log"/"$log_$instance".log &
sleep 10 #Sleep time for the extraction process.
now1=$(date +'%d/%m/%Y %X');
echo -e "*** TSO *** "$now1": Started extraction for MAGIC object type "$log" with name starting "$instance" process PID = "$!""
else
now2=$(date +'%d/%m/%Y %X');
echo -e "*** TSO *** "$now2": Total MQL extraction process reached "$count"....\n*** TSO *** "$now2": waiting for previous process PID "$!" to complete"
wait $!; #Main wait statement when count >=7. Once wait is over, run the next command after wait.
nohup "additional_command_parameters" > /usr/local/app/log/"$log"/"$log_$instance".log &
sleep 10; #Sleep time for the last MQL which was waiting before log files.
now=$(date +'%d/%m/%Y %X');
echo -e "*** TSO *** "$now3": Started extraction for MAGIC object type "$log" with name starting "$instance" process PID = "$!"\n*** TSO *** "$now3": Total number of extraction MQLs on DB are = "$count"\n"
fi
done < $FILE2
This way when 7th process is trying to start, it waits until 6th is completed and so on .....

SYNOPSIS
line
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
line: XCU5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
OPTIONS
None
DESCRIPTION
The line command copies one line, up to and including a newline, from standard input and writes it to standard output. Use this command
within a shell command file to read from your terminal. The line command always writes at least a newline character.
NOTES
The line utility has no internationalization features and is marked LEGACY in XCU Issue 5. Use the read utility instead.
EXIT STATUS
Success. End-of-File.
EXAMPLES
To read a line from the keyboard and append it to a file, enter: echo 'Enter comments for the log:' echo ': c' line >>log
This shell procedure displays the message: Enter comments for the log:
It then reads a line of text from the keyboard and adds it to the end of the file log. The echo ': c' command displays a : (colon)
prompt. See the echo command for information about the c escape sequence.
