[CentOS] easy BASH question

[zGreenfelder]

there are numbers at the start of the line?

e.g. your regex is actually something more like "^[0-9]+ su"
and depending on your unix variant (e.g. not a linux, possibly)
you really mean egrep and not grep (although to a centos list, yes they're
likely actually the same, but it still might be worth noting)
