Question: A Zabbix server I am currently started showing an alert like this:

```
/etc/passwd has been changed on Router

```

Now, on this Router machine I don't have a history of the passwd file so I cannot see exactly what changed, but what I know is that the time of the alert roughly coincided with this `Router` machine being rebooted. As soon as the router came back up, Zabbix started throwing this alert.

Running `ls -l /etc/passwd` on the `Router` device shows that the last modified timestamp is roughly the same as the time of the reboot.

This could be pure coincidence, but I'd rather double check here since I could not find anything online: can a simple device reboot cause the `/etc/passwd` file to be updated (if not in the contents, at least in the timestamp)?

Answer: 
Move the second folder one step up, move the contents, then move the second folder back. Like so:

```
cd folder1
mv folder2 ..
mv * ../folder2/
mv ../folder2 .

```
You are reporting that you are unable to move the contents of one folder to another? Is this the sequence of events you have tried?

```
$ ls folderN
file1 file2 folder1 folder2
$mv folderN/* folder2
mv: cannot move 'folder2 to a subdirectory of itself, `folder2/folder2`
$ls folderN/folder2
file1 file2 folder1

```

`mv folderN/* folderN/folder2` should be the only command you need.
