Bash脚本 - 每次输出后Printf都不会添加新行
[英]Bash script - Printf doesn't add a new line after each output
问题描述
I am trying to use getent to print passwd file for a specified user and want to get a specific output like this (jumping lines included): 
我试图使用getent打印指定用户的passwd文件，并希望获得这样的特定输出（包括跳跃线）：
User: <username>
UID: <user_uid>
Groups: <group 1> <group 2> <group 3>
Home folder: <user's_home_folder>
So I am using this but can't seem to get it right: 所以我使用它但似乎无法正确使用它：
getent passwd foo | awk -F ':' '{printf "%s\n" "User: "$1, "UID: "$3, "Groups: "$4, "Home folder: "$6}'
Am I doing printf wrong? 我在做printf错了吗？

这是正确的方法 ：
getent passwd foo| awk -F ':' '{printf "User: %s\nUID: %s\nGroups: %s\nHome folder: %s\n", $1, $3, $4, $6}'
