Ksh progress bar

Sometimes all we need is a little patience. Or, at least, something to watch while we're waiting. The infamous Progress Bar is an example of such a thing. If your script needs to wait a while, particularly if it needs to wait for a fixed amount of time, this little progress bar may be of help.

For example, you may need to wait for some external process, such as some remote web service, to complete, but you want to give the user something to watch to show that the script has not died.

Other things might be to wait for an entry to appear in DNS, for a virtual machine to complete booting, for a database entry to be created, and so on.

This example is nice and simple to test for, though and quite easy to set up for yourself - just set up a web server with a file "status" in the DocumentRoot. The progress bar shows a row of dots ".

You may have noticed that the function takes up to four arguments - we have just called it with "10" as the width of the progress bar.

You can also specify how long to sleep between dots, and also what character to use for unused and used time slots. To input the special character in vitype this sequence of keystrokes, without the padding spaces:. Or - you can do what the downloaded script does, which is to use Octal characters. It's a bit less convenient, but if you just run man asciiyou can get the Octal forms quite easily.
