Java 11 GC时间戳

Question

$baseDirectory = "C:\Test\Rename\" $a = "\-(.*?)\_" $b = "_" $Include = '*.jpg' Pushd $baseDirectory Get-ChildItem -Filter "*$a*" -Recurse| Rename-Item -NewName {$_.Name -replace $a,$b} -ErrorAction SilentlyContinue PopD 默认情况下不打印时间戳。它只有-Xlog:gc*:/opt/myapp/gc.log。如何将uptimemillis添加到上述vm选项，以便它也可以打印时间戳。 PS：我使用的是Java 11，没有使用time的特权。

Answer 1

这也会打印日期/时间In [4]: np.vstack((a1,a2)) Out[4]: array([[1, 2, 3], [7, 8, 9]]) In [5]: print _4 [[1 2 3] [7 8 9]] In [6]: _4 Out[6]: array([[1, 2, 3], [7, 8, 9]]) In [8]: print repr(_4) array([[1, 2, 3], [7, 8, 9]])
