问题描述：

我有一个逗号分隔的值，例如:

I have a comma separated value like :

package1,package2

我想要一个shell命令将其转换为:

I want a shell command to convert this to:

"package1","package2"

答

如何

$ line='package1,package2'
$ printf '"%s"\n' "${line//,/\",\"}"
"package1","package2"

或

$ IFS=, read -ra fields <<<"$line"
$ printf '"%s"\n' "${fields[@]}" | paste -sd,
"package1","package2"
