grep + 正則表達式匹配位於最後一個單詞之前的單詞

我想擷取最後一個單詞之前有 (XXXX) 單詞的所有行

而 xxxxx - 是數字

/opt/OV/bin/opcagt -status
scopeux     Perf Agent data collector                        (5102)   Running

ovcd        OV Control                          CORE         (5344)   Running
ovconfd     OV Config and Deploy                COREXT       (5383)   Running

我嘗試

/opt/OV/bin/opcagt -status | grep [0-9]

但是這個 grep 語法不能擷取最後一個單詞之前的單詞

預期成績：

嘗試

/opt/OV/bin/opcagt -status |  awk 'NF>2 && $(NF-1) ~ /\([0-9]*\)/ '

在哪裡

• $(NF-1)在最後一個欄位之前匹配
• ~要求 awk 進行模式匹配
• /\([0-0]*\)/模式是(，任意數量的數字和)（您可以使用$$ 0-9 $$$$ 0-9 $$* 至少有一個。
• 預設操作是列印。

在行尾搜尋包含模式(4-digits)<spaces>word的行

grep -E '\([0-9]{4}\)\s*\w+$'
