dash vs bash

后来发现，因为Ubuntu默认的sh是连接到dash的,又因为dash跟bash的不兼容所以出错了.执行时可以把sh换成bash文件名.sh来执行.成功.dash是什么东西,查了一下,应该也是一种shell,貌似用户对它的诟病颇多。

修改sh默认连接到bash的方法：

第一种
sudo dpkg-reconfigure dash
选择no 即可！
再次编译！通过！搞定！
第二种
通过bash命令执行
bash install.sh

go time string

current := time.Now()

fmt.Println("origin : ", current.String())
// origin :  2016-09-02 15:53:07.159994437 +0800 CST

fmt.Println("mm-dd-yyyy : ", current.Format("01-02-2006"))

自定义格式输出某一项

jq '.[0] | {message: .commit.message, name: .commit.committer.name}'  
结果：
{
  "name": "Stephen Dolan",
  "message": "Merge pull request #162 from stedolan/utf8-fixes\n\nUtf8 fixes. Closes #161"
}

自定义格式输出多项

jq '.[] | {message: .commit.message, name: .commit.committer.name}'  
结果：
{
  "name": "Stephen Dolan",
  "message": "Merge pull request #162 from stedolan/utf8-fixes\n\nUtf8 fixes. Closes #161"
}
{
  "name": "Stephen Dolan",
  "message": "Reject all overlong UTF8 sequences."
}

以数组形式自定义输出多项

jq '[.[] | {message: .commit.message, name: .commit.committer.name}]'
