Running meld as administrator

[Andrew <anon_private yahoo com>]

Hello,

I would like to use 'meld' to compare some files kept in /etc folder.

However, I am having problems because I do not have the necessary permission.

Please can you advise the best way for me to use 'meld' in this and similar folders.

I have been told to use kdesu meld. I am not sure if this command is still available to me, or the advisability of its use.

I am using 'meld' under manjaro (Plasma: KDE)

Thanks
