subtracting variables in ksh
hi all,
how do i subract variables in shell ?? am trying to space out the headers and the output generated by the shell so they all line up :

currently the output is like this :


Code:
servers         :      users

server1         :      10
latestServer         :       50



so i thought i would keep a constant e.g 40 and subtract the length of the server name from it.

Code:
count=${#myserver};       # this is the length of the server name
spaces=((40 - $count ));  # this doesnt really work

thanks in advance.
