Question: I am using AQGridView in my project. we need to create a black colored border around each image. Can anyone help me on this. 

Thanks in advance.

Answer: 
```
awk 'BEGIN {max = 0} {if ($6>max) max=$6} END {print max}' yourfile.txt

```
The min can be found by:

```
awk 'BEGIN {min=1000000; max=0;}; { if($2<min && $2 != "") min = $2; if($2>max && $2 != "") max = $2; } END {print min, max}' file

```

This will output the minimum and maximum, comma-separated
