垂直分割 screen 視窗

網路上流傳太多 debian/ubuntu 的 screen 可以垂直分割，但是其他 linux distro 還沒跟進 (更何況是 FreeBSD 及 Mac OSX)，那我們這些人怎辦呢？

其實就是使用 git 版的 screen。

安裝

步驟:

$ git clone git://git.savannah.gnu.org/screen.git
$ cd screen/src
$ ./autogen.sh
$ ./configure
$ make
$ cp screen ~/bin/
$ ... # 進自己的 .<shell>.rc 去修改，比如 alias screen='~/bin/screen'

當然，如果覺得這個 git 版的 screen 要直接取代原本安裝的 screen，那就直接以下面的指令來取代剛剛的後兩個步驟:

$ sudo cp screen /usr/bin/screen # 或是 copy 到 /usr/local/bin/screen (FreeBSD) 等 `which screen` 出現的路徑

使用 (請注意<C-a> 後面按鍵的大小寫)

以下以 <C-a> 表示 Ctrl + a

「切成」垂直分割的視窗:

<C-a> |

「切換」到新生成的垂直視窗:

<C-a> <C-tab> <C-a>

持續「切換」垂直視窗:

<C-a> <tab>  # 就一直 <C-a> 再按 tab

「關閉」垂直分割的功能:

<C-a> Q

水平分割？

應該一般現行 screen 都有，只要把上述使用方法的第一步，改成:

<C-a> S
