Admin password reset not working from Linux Terminal

Cause: If the new admin password contains any special characters, the Linux terminal interprets it as a command.

Resolution or Workaround:  Avoid this issue by using single quotes instead of double quotes. Or use the escape character.

eg:

php resetadminpw.php -p 'he!@#%$%^)*el$AAo'  

OR

php resetadminpw.php -p he\!@#%$%^)*el\$AAo
