     @lanodan @kadei `mkdir () { mkdir $1 && mkdir --rate ☺ || mkdir --rate ☹`

     @lanodan @kadei Too slow;
     #include <stdlib.h>
     int main(){while (1){system("mkdir --rate ☹");}}

     @Suiseiseki @kadei @lanodan omit the type in main to get the compiler warning and it's perfect

     @kadei It's hardly slower when you can't even kill it with C-c and have to find the pid and `kill -9`.

     @Suiseiseki @lanodan I think that'd be slower (other than omitting the sleep) since each system() spawns a fresh shell process

     @kadei @Suiseiseki Yeah, posix_spawn would make more sense, but shells are typically fast enough if all you want to do is execute a ton of commands. After all it can DoS the whole system with a simple forkbomb.

     @kadei @Suiseiseki

     $ clang -O2 -Wall -Wextra -o 1000 1000.c -static $ dumbbench --float -s ./1000 | tail -n 3 1000 cmd: Ran 20 iterations (0 outliers). cmd: Rounded run time per iteration (seconds): 0.614800 +/- 0.002500 (0.4%) $ dumbbench --float -s dash ./1000.sh | tail -n 3 1000 cmd: Ran 20 iterations (0 outliers). cmd: Rounded run time per iteration (seconds): 0.757000 +/- 0.021000 (2.8%)

     So even with the cost of launching a shell it's still reasonably fast.
