如何減少grep命令的輸出？

Question

我正在運行鹽狀態並使用grep來檢索任何失敗的檢查。在默認情況下，輸出下面的文本每一次失敗鹽：

ERROR: Minions returned with non-zero exit code 

我希望削減從我的命令，這個輸出，這樣我可以用實際的故障（例如，其中的細節檢查失敗），以輸出到.html文件將用於顯示我們的環境的當前狀態。

這裏是我的命令：

salt --state-output=terse -C 'ServerName' state.sls ldapchecker test=True | grep 'Result: Failed' 

這裏是輸出：

ERROR: Minions returned with non-zero exit code 
Name: /var/log/stunnel.stunnel.log - Function: file.exists - Result: Failed 

我想會留下失敗的檢查（在/ var /日誌/安全通道的人的路.stunnel.log）

編輯：由於這裏要求是輸出：

salt --state-output=terse -C 'BCA-AJT-LD-01' state.sls ldapchecker test=True 2>/dev/null

Answer 1

如果你想使用單個命令，那麼awk也可以在這裏幫助。

your_command | awk '/^Name:/{print $2}' 

編輯：按照您最新的編輯請你嘗試下面的命令。

your_command | awk '/Name:/ && $2 ~ /\// && $0 ~ /Result: Failed/{print $2}' 

Answer 2

試試這個代碼：

salt --state-output=terse -C 'ServerName' state.sls ldapchecker test=True | grep 'Result: Failed' | awk -F':|-' '{print $2}'
