Ubuntu

Not able to run executable as another user

Asked by passionguy

I ran the following command on a terminal to install Oracle.

./runInstaller -ignoreprereq
bash: ./runInstaller: Permission denied

I created the user for the Oracle installation using this commands below:
sudo groupadd oinstall
sudo groupadd dba
sudo useradd -g oinstall -G dba -p passwd -d /home/oracle -m oracle -s /bin/bash

How could i run this command. Could you also provide a link about creating users & groups & assigning privileges to users thru terminal.

Thanks in advance....

In Ubuntu you can act as your user (normal command) or as root (using sudo), if you want to act as dba user you must login as dba.
But if you want to run ./runinstaller you must run (at the console):
sudo ./runinstaller
Hope this help, let me know

No, that's not correct. As the main user on Ubuntu, you can change your user:

sudo su oinstall

then you can run a program as the other user if it's executable by that user:

./runinstaller

You should probably look at the man page for chmod:
man chmod

To give execute privs to all chmod +x file/dir
