Question : How to write while loop on a single line?

Hi ppl,

I have this one line in my shell script that looks like this:

x=`date +"%H"` ; echo $x ; while [ $x -lt 12 ] ; do ; x=`date +"%H"` ; done

It makes sense to me but when I run it, I get this error:

ksh: syntax error: `;' unexpected

What am I doing wrong?

Remove the ; after the word "do" and it will work
