bash
===
Find last command with prefix

Add the following commands in bashrc

bind '"\x1b\x5b\x41":history-search-backward'
bind '"\x1b\x5b\x42":history-search-forward'

如果鍵盤layout不對，可用以下步驟

首先利用showkey找出鍵盤的代碼
shell>$ showkey -a

Press any keys - Ctrl-D will terminate this program
出現上述提示訊息後，請按下鍵盤的上
^[[A 27 0033 0x1b
91 0133 0x5b
65 0101 0x41

再按鍵盤的下
^[[B 27 0033 0x1b
91 0133 0x5b
66 0102 0x42

最後按下Ctrl+D退開showkey的互動模式，若想要整個系統都支援這個功能時請編輯/etc/bashrc，若只想個人帳號支援請編輯 ~/.bashrc

bashrc
