Data SED (regular expression) problem ---

Hello,

I would like to replace Line 187 of my file named run_example.

The original line is below, including the spaces:
Code:
  celldm(1)   = 6.00,

I want it to become something like
Code:
  celldm(1)   = 6.05,

or
Code:
  celldm(1)   = 6.10,

where the number is stored in a variable called $bulksize . This variable increments properly in my for loop.

I tried doing this:
Code:
cat run_example | sed -e "187 s_  [a-z]*(1)   = _& $bulksize,_" > run_example

Didn't work...

Thank you for your help!
