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.

As a follow up on my recent rsync on ESXi 5.1 post, as – when rsync in ESXi terminates the hard way because of a lost SSH connection – rsync can leave “hidden” files behind.
A small script that recursively shows the hidden files (those starting with a dot) starting from the current directory:
find . -iname ".*"
More of those (including deleting them, filtering for only files or only directories, etc) are at Linux / UNIX: Bash Find And Delete All Hidden Files Directories.
Note: don’t try to outsmart using something like piping through grep "\/\." as that will also match files who’s parent directories are hidden.

Blast from the past, and happy I found back the original blog that pointed me to this: Not a complete failure » Blog Archive » How to copy a file with I/O errors?.
A long while ago, I helped out a friend with a HDD that was partially working. He neede the bits of a file that had become unreadable by regular means.
dd to the rescue: it takes a lot longer, but gets the job done eventually. Eventually can be T+eternity.
Note that you always should copy such a file to another drive, like described in the above blog.
Something like this (the parameters are explained at the dd man page):
dd if=/mounting-path/directory-path/damaged.mp4 of=resurrected.mp4 conv=noerror,sync
Usually for creating disk images, dd works on *n*x, Mac OS X, Windows with for instance Cygwin, ESXi, etc.

lesspipe is a great tool:
lesspipe.sh is an input filter for the pager less as described in less‘s man page. The script allows you to view files with binary content, compressed files, archives and files contained in archives.
… however getting it to run on OpenSUSE was a bit of a journey as it is not part of the standard OpenSUSE 12.x repository. You can only get ‘unstable’ lesspipe packages, of which the Show home:adra / lesspipe – openSUSE Build Service seems to be maintained most frequently.
This is how to install it from there: Read the rest of this entry »

Just append -O and -v to a command-line:
nmap -O -v ip-address
Note you need administrative privileges for this on Mac OS X, so there you run it like this:
sudo nmap -O -v ip-address
If you want to scan more than the default 1000 TCP ports, then use the -p- switch:
sudo nmap -O -v -p- ip-address
For more info about the finger printing algorithms used by nmap:

This is brilliant for learning *nix shell programming:
explainshell.com – match command-line arguments to their help text
explainshell is a tool (with a web interface) capable of parsing man pages, extracting options and explain a given command-line by matching each argument to the relevant help text in the man page.
It has open source code at gitub too: idank/explainshell.

A long time ago I wrote about openSUSE 12.x: “A plain halt will not shutdown the system properly.” « The Wiert Corner – irregular stream of stuff.
Well, today, for the very first time, a plain “reboot” didn’t work on this system either showing the same symptom as the “halt”: it would shutdown all services, but not perform an ACPI power cycle.
Luckily the system is still on ESXi, so I could reboot using the ESXi vSphere client.
