This assumes you were setup for Windows / Linux dual booting until some major event ocurred. You’re sure your Windows installation is in perfect condition, it’s just that grub will not find your Redmon OS.
Follow along for a quick-and-dirty howto to repair your bootloader!
Sometimes we want to pipe a script’s output into grep or less. This is pretty straight forward:
$ my-script.sh | less
But sometimes it just won’t work. That’s when we learn the 2>&1 idiom. The previous example turns into:
There’s your cron job. It’s been running for ages. You want it to stop. Better still, you want it to timeout after a certain amount of time.
You’ll be pleased to know there’s a timeout command available on coreutils (for Linux distros).
You created your VM. You’ve set it up. SSH server is up and running.
Now you want to SSH into it. Oops, you can’t.
Here’s how to do it. It’s really simple.
This is a quick overview on how to deal with arrays, including an iteration example. Arrays are bash specific, so good old shell will yield syntax errors.
With the help of the curly braces notation, this is pretty easy to achieve:
# File Name Without Extension
${VAR%.*}# File Extension
${VAR##*.}
This is the very first in a completely unplanned series: bash shell scripting tutorial. It’s been quite some time since my first contact with bash shell. Since then, I’ve fallen in love with the language. Quite literally, if I may add. From simple to complex maintenance scripts to parallel activities to libraries, I’ve fiddled some.
This series is my humble way of saying thanks to all stackoverflow posts and to Julio Cesar Neves, who wrote the best programming book I’ve ever read. Seriously. These tutorials are also a thank you to an old friend who once taught my very first scripting lesson:
Shell scripting is about piecing together very small programs that do next to nothing on their own but become very very powerful when (spoiler) pipe’d together.
