cli script

Hello; I have a cli script and I want to run it as root. So I run "sh-3.2#BTO.php" when pwd is the directory containing the BTO.php script file. The cli script resides in a server document root dir. It is for changing ownership to server user for specific named files. I am informed that "BTO.php: command not found" I don't do this often enough to be on top of the problem/solution But I don't remember having this problem in the past. I have copied the document root dir and contents and installed the copies in another servers document root. Then I run this cli as root to change all the permissions to server user on new server. There are no phantom spaces in the name and O is not 0 (zero) in the name, or vis versa. Any other possibilities? Thanks for time and attention; Jeff K
