Convert text from lowercase to uppercase
The better alternative to #9756.
I don't think I'd ever use the original command, but this one was so bad I had to post this. Sorry.
1. $(ls) is dumb, and will give errors if you have an alias like "ls -Fs"

Sometimes I need a quick visual way to determine if there is a particular server who is opening too many connections to the database machine.
The sample output, is a display of the values you can change, using this command. After a change of of these settings you will need to reload the box, by typing...wait...wait for IT: 'reload'. This comes in handy when working with the RX hardware, for example, which has a base limitation of 32 (RSTP (802-1w) instances. For all of you paying attention that means if you run RSTP on a RX you can only have 32 VLANs. Sure, you can have common groups of VLANs, like back in the day style MSTP, PVST, PVST+ (and all that old STP (802.1d) mess), before "per vlan spanning-tree", RSTP (802-1w), was made. But who wants to do all that?
