forgot to add: What's the difference between back ticks or quotes and regular single quotes?

text in back ticks is executed via a shell, text in single quotes isn't.

Ok, but how does this relate to a command passed from a php Web page? I don't understand the processus. I use bash on my FreeBSD and have not needed a back quote yet that I can recall... and on WinXP?

In your bash shell, you can use backticks in a similar way to how PHP uses them - to assign the output of a command to a variable. For example: LIST=find . -name '*.php' will fill up the shell variable $LIST with all the files with extension .php below the current directory. You could then do something with that variable, like for FILE in $LIST do cp $FILE $FILE.bak done

which works as long as you can guarantee that none your file names contain spaces ... ;)
