Shell脚本统计主机用户信息_shell用户信息查询程序

通过shell脚本统计主机用户信息，输出结果包括用户名，账户类型（Uid），属组，家目录

#!/bin/bash
#awk -F":" '{print $1,$3,$4,$6}' /etc/passwd >>Userinfo.txt
function UserAndHome()
{
	awk -F":" '{print$1"|"$6}' /etc/passwd >UserAndHome.txt
}
UserAndHome
echo "Username","Type","Group","HomePath">info.csv
for Username in `cat UserAndHome.txt|awk -F"|" '{print$1}'`
do
       	Uid=`id -u $Username`
	if [ $Uid -lt 500 ];
	then
		Type='SysAccount'
	else
	  	Type='PersonalAccount'
	fi
#	echo $Uid>info1.txt
	Grpname=`groups $Username|awk -F": " '{print$2}'`
#	echo $Grpname>info1.txt
     	Home=`cat UserAndHome.txt|grep -w -n "^$Username"|awk -F"|" '{print$2}'`
#	echo "$Username","$Uid","$Grpname">>info1.txt
	echo "$Username","$Type","$Grpname","$Home">>info.csv
done
#cp info.csv /root/Desktop/info.csv
#rm -rf info.csv
rm -rf UserAndHome.txt
 

注意grep的精确匹配，需要用到 -w,-n"^"，不然输出结果会有错误
