<h1 id="incron-簡單介紹">incron 簡單介紹</h1>
|
|
|
|
|
|
<p>incron 是一個Linux 上的小工具，可以用來監控特定目錄，當目錄內容發生變化時，可以執行自訂的script</p>
|
|
|
|
|
|
<p>可以監控的動作如下</p>
|
|
|
|
|
|
<p><img src="https://i.imgur.com/vq5CFZr.png" alt="incron可監控的動作" /></p>
|
|
|
|
|
|
<p>語法範例</p>
|
|
|
|
|
|
<p><code>incrontab -e</code> (編輯)</p>
|
|
|
|
|
|
<p>語法 source_folder/mask(可以用多個不同動作，中間用 , 隔開)/要執行的script</p>
|
|
|
|
|
|
<p><code>
|
|
|
/usr/share/nginx/html/hexoblog/source/_posts/ IN_MODIFY,IN_CREATE,IN_DELETE,IN_MOVE /scripts/run.sh
|
|
|
</code></p>
|
|
|
|
|
|
<p>這行指令是說當 <code>/usr/share/nginx/html/hexoblog/source/_posts/</code> 這個目錄產生變化(修改、新增、刪除、搬移)時，執行 <code>/scripts/run.sh</code> ，當然指令內容就看要怎麼應用。 在 <code>/var/log/cron</code> 裡面可以看到有沒有乖乖聽話在執行

|
|
|
>Jul 12 04:28:21 3cx1 incrond[11814]: (root) CMD (/scripts/run.sh)<br />
|
|
|
>Jul 12 04:28:21 3cx1 incrond[11814]: (root) CMD (/scripts/run.sh)</p>
|
|
|
|
|
|
<p>有點像是之前玩過的 lsyncd / inotify 的工具</p>
|
|
|
|
|
|
<p>目前是拿來作為自動偵測並發布Hexo Blog的「手段」，先透過win-sshfs之類的工具，mount 伺服器上的 Hexo Blog 的<code>source/_posts</code>目錄，然後在本地端的筆電上用Markdown editor編輯文章後，直接存在這個掛進來的目錄，然後透過 incron去自動執行hexo generate的指令，還滿方便的！</p>
