Hi Experts,

I have done the required setup to execute unix OS commands using Java class as mentioned in the link( https://oracle-base.com/articles/8i/shell-commands-from-plsql ) from database programs , I was able to run echo command from the Pl/SQL program, however for any other executable commands I need prefix /bin eg. to do a ls I need to use the syntax as shown below
<
BEGIN
unix_command('/bin/ls -lrt');
end;
/>

Also some of commands are not working like "tee command" where I am getting the below error.

line 25: tee: No such file or directory

So in this regard I request to help me out to able to execute the script without prefix as /bin and also to allow the usage of tee command.

Thanks.
