“产出”；linux shell“；vs"；php系统（）分类

让我们执行以下命令：

# zcat -f /var/log/remotelog*|grep -e "10\.0\.1\.15"|grep -e "7,35)"|sort -k 1M -k 2r|tail -n 250 3>&1

得到如下输出：

非常好

但我是这样做的：

<?php
$e = "zcat -f /var/log/remotelog*|grep -e \"10\.0\.1\.15\"|grep -e \"7,35)\"|sort -k 1M -k 2r|tail -n 250 3>&1";
system($e, $ret);
echo $ret ;
?>

为什么?？我不明白…

如果我理解正确，第二个（通过PHP）是“正确”的输出

由于列表首先按月份名称排序，并且月份名称取决于区域设置，因此我怀疑区域设置（LC_*环境变量）在命令行和PHP中是不同的，这会影响排序的输出。

你说得对。现在看起来很明显-我在排序之前添加了env LC_ALL=pl_pl，现在它就像一个符咒。谢谢！
