hey sorry, i wrote the description but don't lnow how it got erased.

i have a set of commands inside a text file. 1 command per line.
command.txt
Code:
echo "start"
ls -l
pwd

i want to execute these commands one by one and after finishing the last command, again it should start from the 1st command.

infinity.sh
Code:
count=0
while :
do
        while read exe_command
        do
                (( count++ ));
                echo "$exe_command"
                result_$count=`$exe_command`
        done < command.txt
        echo ""
done

the commands are not getting executed.

output:
e
Code:
cho "start"
infinite.sh: line 8: result_178="start": command not found
ls -l
infinite.sh: line 8: result_179=total: command not found
pwd
infinite.sh: line 8: result_180=/home: No such file or directory
