Or:
Code:
awk 'NR==1{p="cool:"$0};$0~p{x=1;print;next};/cool:/{exit};x' b.txt c1.txt

Use nawk or /usr/xpg4/bin/awk on Solaris.

A possible solution:
Code:
awk '
   NR==FNR {               # First file (keys)
      keys["cool:" $0]++;  # Memorize keys for second file
      next;                # Next record
   }
   /^cool:/ {              # Record start with "cool:"
      display = ($0 in keys ? 1 : 0);  # If memorized key display block (1)
   }
   display                 # Display line if block must be displayed
    ' b a
