[CentOS] yum history list

Hi List,

I have several workstations all with exactly the same OS versions, kernels + yum versions;

CentOS Linux release 7.2.1511 (Core) kernel.x86_64 3.10.0-327.28.3.el7 yum.noarch 3.4.3-132.el7.centos.0.1

running a 'yum history list' command produces different outputs on some workstations, I haven't changed any yum configurations.

Workstation A: yum history list Loaded plugins: fastestmirror, langpacks ID | Login user | Date and time | Action(s) | Altered

Workstation B: yum history list Loaded plugins: fastestmirror, langpacks ID | Command line | Date and time | Action(s) | Altered

Any clue as to why I have different fields being output?

I see in the yum manual: In "history list" you can change the behaviour of the 2nd column via the configuration option history_list_view.

But I'm unsure how I can adjust the columns.

Any clues would be much appreciated,

Thanks,

Michael
