• 您不需要保留迭代器来添加到数组.你可以简单地做 array+=(item)(not array+=item).
• 获取输入中的列就像使用带有多个目标变量的 read 一样简单.作为奖励，最后一个变量获得第 N 个词和所有后续词.参见 help [r]ead.
• You don't need to keep an iterator to add to arrays. You can simply do array+=(item) (not array+=item).
• Getting the columns in the input is as simple as using read with multiple target variables. As a bonus, the last variable gets the Nth word and all subsequent words. See help [r]ead.

这节省了大量的叉子，但我还没有测试它有多快.

This saves a ton of forks, but I haven't tested how fast it is.

ogl_commands=()

while read -r date1 date2 time server id type pid commands
do
    ogl_date+=("$date1 $date2")

    ogl_commands+=("$commands")
