I had it in my head that I could sort internally with -s and re-sort the output based on -F, but it doesn't seem to be working that way. For example with ./perf mem record -a grep -r foo /* > /dev/null ./perf mem report -F overhead,symbol_daddr,pid -s symbol_daddr,pid --stdio I was thinking I could sort everything based on the symbol_daddr and pid. Then re-sort the output to display the highest 'symbol_daddr,pid' pair. But it didn't seem to work that way. Instead it seems like I get the original sort just displayed in the -F format. Did I misunderstand what the -F can do or I am using it wrong?
