secureCRT 日志儲存并記錄每條記錄的時間

​

對于嵌入式工程師來說，和裝置互動是工作中必不可少的事。

在同僚中序列槽工具一般都是使用secureCRT 和Xshel ，具體那個好在此不做讨論。我覺得都很好，看個人喜好。

對于嵌入式系統工程師來說，系統的啟動時間是個重要名額。是以能夠準确測量系統每個子產品所用時間尤其重要。

下面介紹一下在使用secureCRT過程中一個很好用的技巧，儲存每條記錄并列印記錄的時間

先看看儲存日志的效果

以上是Linux啟動過程中儲存的log日志，嵌入式系統工程師是否很興奮。啟動的每個過程都有時間。怎麼做的？

[點選并拖拽以移動]

打開secureCRT 工具欄的《選項》--《回話選項》就彈出上圖。點選《日志檔案》--《在每行》中添加 %h:%m:%s:%t 确定

此時配置已經完畢。下一步 工具欄 《檔案》---選中《會話位置》，選擇log日志存放位置。

重新開機系統之後，再斷開序列槽連結檢視日志
