Displaying variables
The display command is how you produce a text version of the contents of any variable. Various commands display text, making it natural to display information about the run while a script is executing.
quietmsg(s): displays the string s in the console,
msg(s): like quietmsg(s), but brings the console to the front,
postit s displays a message in the floating Message window. postit "" closes the floating Message window.
postit "job in progress …"
set x to 1
quietmsg(x)
set x to x + 1
quietmsg(x)

Applescript: Run or Call a Shell Script

How do run a shell script with an AppleScript? How do I integrate shell scripts into AppleScript? 
How do I call a shell script called /path/to/chkhost.sh using an applescript?

AppleScript is a scripting for Mac OS. It is the Mac OS scripting interface, which is meant to operate in parallel with the graphical user interface. With AppleScript, you can control, and communicate among, applications, databases, networks, Web services, and even the operating system itself.

Running Shell Commands From AppleScript Scripts
You can easily execute shell commands from your AppleScript using the following syntax:

Gem installs can be slooow. One of the biggest culprits is documentation. Every time you install a gem, your computer has to scan the source of that gem and generate documentation.

This can be useful if you often need to check gem documentation when you're offline. Just run  gem server and point your browser at http://localhost:8808 to access them. The ri command is also handy to search documentation from the terminal.

But if you're like me, you probably don't use local docs. You probably have a decent internet connection at most times. So the time spent generating documentation is just time wasted.

If you're using bundler to install all of your gems, you don't have to do anything. Bundler skips rdoc/ri by default. If you happen to be using the gem command directly, you'll need to do a bit of configuration.

You may already know that you can disable rdoc/ri generation when you run gem install, by passing in certain flags.
