对不起，我是第一次来这里，只能提问...
使用建议：
valgrind --tool = massif --pages-as-heap = yes - massif-out-file = massif.out ./test.sh; grep mem_heap_Bmassif.out | sed -e's / mem_heap_B =( . *)/ \ 1 /'| sort -g |尾巴-n 1
然后grep mem_heap_B massif.out ... mem_heap_B = 1150976 mem_heap_B = 1150976 ...
这与“top”命令在类似时刻显示的内容非常不同：
14673 gu27mox 20 0 3280404 468380 19176 R 100.0 2.9 6：08.84 pwanew_3pic_com
来自valgrind的测量单位是什么？
该
/ usr / bin / time -v ./test.sh
永远不会回答 - 您必须直接将可执行文件提供给/ usr / bin / time，如：
/ usr / bin / time -v pwanew_3pic_compass_2008florian3_dfunc.static card_0.100-0.141_31212_resubmit1.dat_1.140_1.180 1.140 1.180 31212
