Re: Newbie Variable Question

hello,

I have a Variable that is a single numeric value, let's say it's "1" or
"8". Is there a way to make that Variable into "01" or "08".

Basically its a variable that gets the current day. So in my script, I
calculate the current day and populate that variable.

But later on in the script, I need that value to be 2 digits, not 1
digit. So if today is August 9th, the variable will be "9", but I need
"09".

Any suggestions?

Thanks!


Are you sure that needs to be one digiti initially? You might be better off just using the 2-digit format everywhere. Anyway, to your question:
If your shell supports printf:

$ printf "%02d\n" 1
01
$ printf "%02d\n" 10
10
$ printf "%02d\n" 100
100

Ed.
