Need help with Using Head in a script.

[millsra]

I am new to scripting so I appreiciate any help that I can get. I am under the gun right now and this is the last part to get this to work.

$len is equal to the number of entries in a file minus the newest entry.
I am trying to use my variable of $len in my head command. Something is not right here but I can not figure it out. Maybe I have been beating my head agaist a wall too long that it all looks the same right now.

head -n '-${len}' /usr/local/emc/util/tmp


Any assistance would be appriecaiatd.

Why using single quotes that prevent shell expansion ?
