从上面的给定行中，我想提取任务No的值，即'128'和'16'ptile.想在变量中读取此值

from the above given line, I want to extract the values No of tasks i.e '128' and '16' ptile. want to read this values in variable

任务= 128ptile = 16

Task = 128 ptile = 16

推荐答案

您可以将 grep -P 与 read 一起使用:

read task ptile < <(grep -oP '.*\K\b\d+(?= Task)|.*ptile=\K\d+' file | tr '\n' ' ')

echo "[$task] - [$ptile]"
[128] - [16]
