Actually, xargs (and any implementation of it) cares about the limit itself. That's what it is made for. You would limit the number of args with "-n" if the executed program can only handle up to that number, or if the logic requires it, e.g. when input comes in as pairs: $ seq 6 | xargs -n2 echo diff -u diff -u 1 2 diff -u 3 4 diff -u 5 6 There's no need to worry about the other end of the range. So in your patch, just omit the -n (and getconf). Have a nice day, Berny
