No, you could script it out of top(1), but I'm going to guess that you're trying to be warned when the system is close to running out of memory. That is silly -- you paid for the memory; why would you *want* it to sit around doing nothing? Also note that the definition of "free" is somewhat complicated. Maybe if you described the actual problem you want to solve, we could suggest a more appropriate answer. A literal answer to your question might be: top -d 1|grep '^Mem:'|cut -d ',' -f 6 assuming the format of the line of top doesn't change.
