Linux

• Check current file format

:set ff?

• Set file format to UNIX

:set ff=unix

When you pasting text from other sources into Vim using mouse right-click, the format may be messed up due to auto-indenting. Use the following command to enable pasting mode:

:set paste

After the pasting is done, revert to normal mode:

:set nopaste

Unix-like作業系統關係圖

• Unix-like作業系統，包含了Unix的衍生系統以及與Unix類似的系統
  • Unix的直系衍生系統：FreeBSD, macOS…
  • Unix類似的系統（獨立開發）：Linux, Minix…

• 因此Linux及macOS都是Unix-like作業系統，但Linux是獨立於Unix開發，而macOS是基於BSD開發的系統

To enable mouse scrolling for screen sessions, just put this line into your ~/.screenrc file:

termcapinfo xterm* ti@:te@

To test if it works, you must re-attach your sessions.

• 開啟本機的8888 port，通過此port的請求會全部交給remote-host處理(藉由兩者的ssh連線)，此時再把本機的proxy設定成SOCKS localhost:8888，可以達到完全的proxy效果。

ssh -D 8888 -N user@remote-host

• 開啟本機的8888 port，通過此port的請求會全部通過remote-host到達target-host:80

ssh -N -L 8888:target-host:80 user@remote-host
