Sort, group rows
I wrote script in bash which generates this report:

User1,admin,rep,User2,shell,path1,x1,r1
User2,admin,rep,User7,shell,path1,x1,r1
User3,admin,rep,User4,shell,path1,x1,r1
User4,admin,rep,User3,shell,path1,x1,r1
User5,admin,rep,User1,shell,path1,x1,r1
User6,admin,rep,User5,shell,path1,x1,r1
User7,admin,rep,User6,shell,path1,x1,r1
...

I would like so that (UserX):

User1,admin,rep,User1,shell,path1,x1,r1
User2,admin,rep,User2,shell,path1,x1,r1
User3,admin,rep,User3,shell,path1,x1,r1
User4,admin,rep,User4,shell,path1,x1,r1
User5,admin,rep,User5,shell,path1,x1,r1
User6,admin,rep,User6,shell,path1,x1,r1
User7,admin,rep,User7,shell,path1,x1,r1
...

How to do this ?
Thx

User9,admin,rep,,,path1,x1,r1
User10,admin,rep,,,path1,x1,r1
