If statement

Hi i am trying to set up an IF statement that says if FILE1 exists or FILE2 exists do a command. I am struggling to remember what i need to put in for the OR statement. i have the following

if [ -a $FILE1 (or?) -a $FILE2 ]
then
run my command
fi

Would a | command work?

I got the solution, you need to put -a.

Just for info, newer shells like bash and ksh allow more "usual" short circuit operator syntax of && and || so you can do things like

[[ -d file1 && -d file2 ]] || echo "Both files are not directories"

i.e. with && for AND, || for OR
