Hi,

How to use the pstree command.  
I tried to execute as below, not able to interpret/understand the output.

```nohighlight
pstree -p | grep 525

```

OUTPUT:

```nohighlight
 
 
[xx@yy ~]$ pstree -p | grep 525
        ��scsi_eh_0(525)

```

Can anyone throw some light on this?

Many thanks.

Rgds,
