vi in Linux

Ｗ. 上下右左會出現ABCD in the insert mode

vi ~/.vimrcset nocompatible

Q. It doesn't work with MacVim (and GUI Vim). I'm only able to delete text from the line I'm in. If I switch to normal mode or if I move the cursor to another line I'm not able to delete text with backspace anymore and I have to delete it with 'x' in normal mode.

set backspace+=indent,eol,start set backspace=2

Q. color for c language

:syntax on

Q. disconnection

ServerAliveInterval 60 sec

u	復原前一個動作。(常用)
[Ctrl]+r	重做上一個動作。(常用)

Q. Page down, Page up.

Then CTRL-B and CTRL-F should do the trick.

Command in Linux - find

初步概念

最近一直在做一些資料整理，但總覺得一個一個搬檔案殺檔案，真的是件很瑣碎的事情，於是就想了一些辦法能夠減少這樣的次數。

Work Env.

find \. -name "*.png" -exec ./$1 {} {}.z \;

Piggy Note

我想發明電腦就是要為了能夠幫助人處理一些瑣碎的事情

vimdiff

初步概念

在Team work的作業環境下，該如何將別人的程式有效的結合自己的程式，當然你可以一份一份的將程式碼看過一遍，在區分找出不同之處加以修改，不過這樣的過程非常耗時且毫無效率可言，於是就有人想出該如何利用其他工具來達到目的，vimdiff就是用來分辨兩者的程式碼有何不同且能修改程式。

Work Env.

#apt-get install vim-full

do - Get changes from other window into the current window.

dp - Put the changes from current window into the other window.

]c - Jump to the next change.

[c - Jump to the previous change.

Ctrl W + Ctrl W - Switch to the other split window.

:diffupdate - diff update

:syntax off - syntax off

zo - open folded text

zc - close folded text

Piggy Note

在Windows裡用了許多好用的軟體作為寫程式的輔助，但在Linux中的概念總覺得不太方便界面不人性化，不過在vimdiff中打破這項觀念，這套軟體真的可以跟beyond compare作抗衡。
