I need to take the average run time and CPU de 30 execuções consumption of a program done in Python . I have to use the command time of Linux . Since I've never worked with Linux before I'm having trouble doing this.
This is the code I have made so far (not working). Could someone help me make this work?
size=400
n_cpu=4
/usr/bin/time -f "CPU: %p TIME: %e"
for i in {1..30};
do
python "script.py" $size $size $n_cpu
done
python -m timeit -n 30 script.py <…parâmetros…>
timeit is a default Python module, which protects you from all associated pranks with timing Python code (eg when you change the code, Python "recompiles" the code you wrote; this time is discounted by timeit but not by Bash).
To get only the time, you can use date
t0=$(date +%s)
for i in {1..5};
do
sleep 1;
done
tf=$(date +%s)
echo "tempo de execução: $((tf - t0))"
To use the team the way you tried it, you need to loop in a new section of bash with the -c
/usr/bin/time -f "CPU: %p TIME: %e" bash -c "
for i in {1..5};
do
sleep 1;
done "
