I wasn't totally sure if I should have posted this here, serverfault or linux and unix but...
我不确定我是否应该在这里发布这个，serverfault或者linux和unix，但是…
What I'm trying to do here is take the output from this command:
这里我要做的是从这个命令中获取输出:
ps -eo pid -eo ecpu -eo command | sort -k 2 -r | grep -v PID | grep -i frmweb
... and apply a filter to which it only looks at processes that are using cpu. ( > 0 )
…并应用一个过滤器，它只查看正在使用cpu的进程。(> 0)
... and then take what's left and push the PIDs (first column) into an array.
…然后取出剩下的，将pid(第一列)推到一个数组中。

To put the process IDs in a bash array called nonzero:
将进程id放在一个称为nonzero的bash数组中:
nonzero=($(ps -eo pid -eo ecpu -eo command | sort -k 2 -r | awk '/frmweb/ && !/PID/ && $2+0>0{print $1}'))
awk commands have the form of condition {commands}. Here, the condition consists of three conditions and-ed together (&& means logical-and):
awk命令具有条件{命令}的形式。在这里，条件包含三个条件，并且一起(&& &表示逻辑的-和):
/frmweb/ && !/PID/ && $2+0>0
-
The first condition says that the line must contain
frmweb.第一个条件是行必须包含frmweb。
-
The second requires that it must not contain
PID第二个要求它不能包含PID
-
The third requires that the second column, denoted in
awkby$2, be greater than zero.Awkcan do both string and numeric comparisons. Although likely not necessary here, the use of addition, as in$2+0, forces the use of numeric comparison.第三行要求awk中用$2表示的第二列大于0。Awk可以同时进行字符串和数值比较。虽然在这里可能没有必要，但是使用加法，如$2+0，强制使用数值比较。
If all three conditions are met, the first column (the process ID) is printed via:
如果满足这三种条件，则通过以下方式打印第一列(流程ID):
print $1
Note that awk removes the need for the two grep commands.
注意，awk不需要两个grep命令。
