Thanks Robert Gamble, ephemient and Jonathan Leffler. Be sure to read the top two answers and comments for full details.
Until now, I always used $* to pass on arguments from *nux shells (bash, sh, ash, etc.). Works on ESXi as well. But that is not the correct way to do.
But “$@” is the correct way:
- Use “$@” to represent all the arguments:
for var in "$@"
do
echo "$var"
done
- As a shortcut,
for var; do ...; done means for var in "$@"; do ...; done
- Basic thesis: “$@” is correct, and $* (unquoted) is almost always wrong. This is because “$@” works fine when arguments contain spaces, and works the same as $* when they don’t. In some circumstances, “$*” is OK too, but “$@” usually (but not always) works in the same places. Unquoted, $@ and $* are equivalent (and almost always wrong).
This next to the following construct makes file processing in *nix a breeze:
for filename in *.7z; do if 7za t $filename 2>&1 > /dev/null; then echo $filename passed; else echo $filename failed; fi; done

The upside of findstr is that it is included with Windows since a long time (at least since Windows XP, later: indeed since Windows ME) and supports a form of regex.
But often it drives you crazy.
When it does, read What are the undocumented features and limitations of the Windows FINDSTR command? – Stack Overflow.

Interesting: Time Machine for every Unix out there – IMHO.
But be careful with the hardlinks, as making a backup of the backup might fail:

Brilliant piece of open source:
SmallestDotNet – SmallestDotNet.com is a single page site that does one thing. It tells you the smallest, easiest download you’d need to get the .NET Framework on your system.
Even on Mac OS X it is helpful and recommends Mono and on iOS it recommends looking at MonoTouch.
Thanks Scott Hanselman for making this available!

Must have on a Mac when you use terminal; either installation way is fine. I got mc from louise, as that was the first one I found.

RouterOS runs on many kinds of hardware. Of course on the MikroTik hardware itself (which always comes with a license), but also on x86 hardware, even virtualized systems.
In that respect, it looks a bit like pfSense, or Endian, but on steroids and closed source.
Here are some links focused on MikroTik on ESXi (which is great for experimental purposes):

Sound of facepalm hitting my head, as I totally by accident found out that as of Windows 8 (un)mounting of ISO files is built into Windows.
Mounting
- Open the folder where you’ve stored your ISO file.
- Right-click on the ISO and select Mount
- You’ll now see the ISO mounted inside your Computer.
- That’s it!
Unmounting:
- Open Computer on your PC.
- Right-click on the virtual drive that was created while mounting ISO file and select Eject.
- The drive disappears after the ISO image is “ejected”.
- That’s it!

IBM isn’t all about dry corporate stuff and sometimes hard to read redbook documentation (:
I love the way they lead you do build your own VI cheat sheet step by step in vi intro — the cheat sheet method.
It is basically a vi tutorial that helps you to build up your own cheat sheet.

There is an interesting post by TinkerTry IT @ home | VMware Workstation 10 released Sept. 4 2013, but you might be fine with the free VMware Player 6 Plus that helped me making up my decision what to buy.
Basically you have these products on the non-server side of things:
(Note: you can find many downloads through Google search for site:www.vmware.com/go)
I bought these:
- VMware Fusion 6
- VMware Workstation 10
My reasoning: Read the rest of this entry »
