Having a slight bit of trouble trying to parse out this one in my head. I'm creating a script in korn shell to find if a file system has at least 5GB. If it does not have 5GB, I want the script to error out.

My code to find the available space is 

```
df -g /u00 | sed -n '2p' | awk '{print $3}'

```

I am using this in an `if` statement like 

```
if df -g /u00 | sed -n '2p' | awk '{print $3}' -lt "5.00";
then
#There's less than 5gb
echo "There's less than 5GB, please clear up space to continue"
exit 1
else
echo "Enough space, continuing"
fi

```

The error I'm getting is 

```
awk: 0602-533 Cannot find or open file -lt.
 The source line number is 1.
Enough space, continuing

```

Obviously, it's not liking where I'm putting `-lt` in this, and I assume it's the fact that I'm trying to combine it with `awk`. Problem is, I'm not sure how to write it to where it won't choke next to the `awk` statement. Is there a better way to do the compare, or am I passing it to `-lt` incorrectly?

I've also tried passing it as a variable like 

```
export AWK=df -g /u00 | sed -n '2p' | awk '{print $3}'
if [$AWK -lt "5.00"];
then
#There's less than 5gb
echo "There's less than 5GB, please clear up space to continue"
exit 1
else
echo "Enough space, continuing"
fi

```

And it doesn't seem to like that either
