Hi,
I’m french and literally one. So I’m not really easy with Sheakespeare language. So, accept my apologies.
As write in subject, I’m a newbie about CentOS an all RedHat declines. I wrote a Shell script for ours Debians (all sort of Debian like) which verify which packets are present before running. I thought I had found an equivalent with « yum list installed | grep <packet> » command but I have sometime alerts about a lock because an other instance of « yum » is running.
I don’t understand why a simple « yum list » impose that! I suppose, like with « aptitude search », it is an understanding scorie.
I’m sure there is an other way to do what I want to do: just verify if a packet is, or not, installed.
Help?
Thanks
