Shell Programming

I'm knid of new to shell script programming. Not a newbie, but not a master either.

Could anybody tell me what's going on here?

I want to write a line that says the actual date in a file. The filename is stored in the variable $config

I added this command to the script:

Code:

echo date $(date) > $config

But when ir runs,I get this error message:

Code:

/sbin/dhclient-script: line 39: $config: ambiguous redirect

I'm writing a hook for dhclient-script

What's going on? I bet it's basic stuff

Can a mod move this to programming please?

Maybe this?

Code:

#put date at beginning of file:
cp "$config" temp
date > "$config"
cat temp >> "$config"


#put date at end of file:
date >> "$config"

The problem was that I wasn't setting the variable the right way. In other words, it was empty.

Sorry to bother in this forum. It wasn't my intention to.
