Executing bash file with sudo for the second time, leads to permission denied, for commands
I have a script that checks if the script has been ran with sudo. If the script is not ran as sudo, the current script is being executed with exec sudo bash. You are asked for a password, you type in the password, success. Everything is perfect - the commands inside the script are ran as sudo. However, the second time you run the script, you are getting cat: /etc/sudoers: Permission denied
Hi All,
When I execute a command on Unix and it says 'Permission denied'. What could be the reason and how can it be resolved?
Many thanks,

fence_virsh
FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)NAME
fence_virsh - Fence agent for virsh
DESCRIPTION
fence_virsh is an I/O Fencing agent which can be used with the virtual machines managed by libvirt. It logs via ssh to a dom0 and there run
virsh command, which does all work.
By default, virsh needs root account to do properly work. So you must allow ssh login in your sshd_config.
fence_virsh accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent.
fence_virsh can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
