Linux: Ifconfig and its replacement

Recently I installed CentOS 7 Minimal, and lo and behold, command not found. As it turns out, ifconfig while you can still get via ‘yum install net-tools‘, we should be a bit more forward looking, and use it’s designated replacement.

To quote Doug Vitale’s excellent article:

some Linux tools that, while still included and functional in many Linux distributions, are actually considered deprecated and therefore should be phased out in favor of more modern replacements.

Specifically, the deprecated Linux networking commands in question are: arp, ifconfigiptunnel, iwconfig, nameif, netstat, and route. These programs (except iwconfig) are included in the net-tools package that has been unmaintained for years.

Now, his article was written in 2011, so this probably means a decade or so after the software was essentially abandoned, there are still unknowing users like me who had no idea, happily using it for whatever we use it for.

So software and blog posts, the gift that keeps on giving then!


Hiding page breaks in Excel

I’d successfully hidden ’em distracting grid lines in Excel via (Ribbon) > View > Gridlines, but then I wanted to hide (similarly distracting) page breaks. As it turns out, this option is pretty well hidden:

File > Options > Advanced > Display options for this worksheet > Show page breaks

Also note that this option is set on a per-worksheet basis, so you’ll have to uncheck once for every worksheet you may have. Thankfully, there is a drop list 3 check boxes above, so just rinse and repeat.

Kudos to the ExtendOffice blog post for this enlightenment:
