Should be simple, possibly even just a syntax help...

I have a huge script, but in it I have a variable that increments... I want to pass this variable to a command such a head or tail I.E.

$inc is my variable that increments up...

I want to execute the command head with the "-n" option to specify how many lines I want it to head....

head -3 will return the top three lines..
I want somehow to do :
head -$inc

but that doesn't seem to work...
