[Git] commit template

1). commit的template
git config --global commit.template [檔案名]
ex: git config --global commit.template ~/.git_template

※應用：
1). script: 將template寫在一隻檔案，並設定git config
#!/bin/sh

### function define ###

git_template()
{
cat << EOF > ~/.git_template
[Topic]:
[Release Note]:
[Involve]:
[Comments]:
EOF
}

### entry point ###

git_template

git config --global commit.template ~/.git_template

[Android] ICS codebase build code command

1). ICS codebase build code command
$ source build/envsetup.sh
$ choosecombo [choose_method]
$ make -j4 (or -j8)

[MySQL][Gerrit] 產出三個report紀錄_view

※說明：
● 將原本建table改成建view
● 因view無法建key，原本在change_messages2建index key，刪掉重複的資料
● 改成下group by，每筆change_id只要列一筆資料就好

[MySQL][Gerrit] 產出三個report紀錄

※備註-Gerrit內建所需表格說明：
● [accounts]：帳號id及name
● [changes]：列出所有changes的資料(RD上到gerrit的code)
● [changes_messages]：列出reviewer、gerrit系統回覆change的資料

※說明：
● 產出三個表格，Wei會將此表格轉成excel
● [report_sheet1]：列出reviewer花了多久時間回覆RD上的code
● [report_sheet2]：列出被reviewer reject的change及狀態
● [report_sheet3]：列出沒有commit rule的關鍵字
