I edited your question to make it readable - but I think it is working as expected once the format is cleaned up. It looks like you are trying to find out if apache2 is running.

#!/bin/bash

if [ $(ps aux | grep apache2 | wc -l) -gt 1 ]; then
  echo "Statistic:0"
else
  echo "Statistic:1"
fi

exit 0

Depending on what "flavor" of linux you are running, the following might be a better option for you. You can also use is-enabled, is-failed, to check other status.

if systemctl is-active -q apache2; then
  echo "Statistic:0"
else
  echo "Statistic:1"
fi

Your script is working absolutely fine as per the code. Please define what kind of error you got.

Try running it on another machine like VMs or containers.
