Driver,

My point was that in awk you can use start/end pairs. i.e. two patterns or conditions sepated by a comma. All you have to do is determine what the conditions are.

My post works with the sample supplied. But with the sample you have supplied, the end condition might be "/^}$/" , i.e. a line that is one "}" on its own with no whitespace. So you would have...

awk '/sub foo/,/^}$/' file

...which could be the simplest solution, but perhaps more work is needed.

It would be more efficient to use "exit" to stop reading the file when the end condition is reached. The idea of counting matched braces can be coded more simply as ....

awk '/sub foo/,0 {print;b+=gsub("\{","{");b-=gsub("\}","}");if(b==0)exit}' file
