Quick question

Hello all,

Quick question from a fairly new to Unix developer.

if [ -a $logfile ]
then
completedLogFile=$logfile.$(date +%Y%m%d-%H:%M:%S)
mv $logfile $completedLogFile
fi

I understand that this portion of code is simply copying a tmp logfile to a completed logfile when a condition is true. The problem is I'm not sure what the comparative expression is(the part in bold). Could any one clear this up for me?

Thanks in advance,

Johnny
