After some manipulations (i don't know, which excatly did it) i unexpectedly broke terminal autocomplete feature. Each time i try yo use it i get:

nimga@ubuntu17:~$ sudo systemctl res-bash: /dev/null: Permission denied
bash: _upvars: `-a4': invalid number specifier
-bash: /dev/null: Permission denied
bash: _upvars: `-a0': invalid number specifier

According to text above i tried to autocomplete "sudo systemctl restart" but got an error. What can i do with it?

What's the output of stat /dev/null? – muru Jul 13 '17 at 11:38
File: '/dev/null' Size: 28 Blocks: 8 IO Block: 4096 regular file Device: 6h/6d Inode: 515 Links: 1 Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2017-07-13 07:42:05.193600092 +0300 Modify: 2017-07-13 14:35:01.493288395 +0300 Change: 2017-07-13 14:35:01.493288395 +0300 Birth: - – darth jemico Jul 13 '17 at 11:45
You broke your /dev/null. See dupe on how to fix it. – muru Jul 13 '17 at 11:47
Did as it mentioned in dupe, but nothing changed. – darth jemico Jul 13 '17 at 12:00
stat /dev/null is still the same? – muru Jul 13 '17 at 12:13
Executed commands from root and it solved the problem. After user's execution permissions were not proper. Thanks for help! – darth jemico Jul 13 '17 at 12:18
