Shell 快速鍵
- [參考] Linux Shell Editing Shortcuts
CTRL + A = 把游標移到行首 CTRL + E = 把游標移到行尾 CTRL + K = 從游標位置往後刪除到行尾 CTRL + U = 把指令全部清掉 CTRL + W = 往前刪除一個參數(到空白處)

$ seq -w 20 ### 會列出 01~20 的數列 (哇!!會補零耶!!) $ fuser /home/jazz ### 會列出目前正在使用這個目錄的 process $ reset ### 把畫面清空(Ex. 不小心 cat 到二進位檔而佈滿亂碼的時候) $ ethtool -i eth0 ### 會列出網路卡的韌體資訊(cool!) 另外,還蠻常用,卻老會忘記的 shell script 技巧: expr P = 1 P = $(expr $P + 1) ### 如果用 P = $(P+1) 是不行的啦~
