I don't think you can look at an array like its a string like that.
Maybe string( @ARGV ) != 1 might work. But what you probably want is:

Hi thanks for looking at the script..
Just to clarify, the scipt runs perfectly if $input it hardcoded eg

thus if the process is running then it exits, if the process is not

exec /etc/init.d/$input restart ;
But if I use $input=$ARGV[0] to give the process

What is $ARGV[$count]? Is it supposed to be

Either use:

Or:
while (ARGV) {
