  • [備忘] ​觀看變動的檔案 posted by Thomas 
    有些時候要盯著某些log，有哪些指令可以不斷看檔案的檔尾呢？

tail -f file
watch ‘tail file’

最近學到的新招式：

less file + <End> + <F>

其中比要好用的應該是 less, 因為他還可以搜尋檔案內容
  • 如何關掉 VMWare Server for Linux 網路介面 vmnet1 跟 vmnet8 的 DHCP 服務？
    • [參考] ​How to disable host only networking dhcp server on Linux hosts
    • [解法] 我直接把 /etc/vmware/vmnet1/dhcpd 更名為 /etc/vmware/vmnet1/_dhcpd，再重跑 /usr/lib/vmware/net-services.sh restart 即可。 
      $ sudo mv /etc/vmware/vmnet1/dhcpd /etc/vmware/vmnet1/_dhcpd
$ sudo /usr/lib/vmware/net-services.sh restart
