Contests of a file is as follows:

cat -n /tmp/my_file

 1  verify(abc) {

 2    foo : bar;

 3    sub1(aa) {

 4    line1;

 5    } 

 6    sub2 (bb) {

 7    line1;

 8    // this line is a comment and must be ignored

 9    line2;

10       sub3 (cc) {

11       line1;

12     }

13    }  

14  }

15  

16  verify(efg) {

17    foo : bar;

18    sub1(aa) {

19    line1;

20    } 

21    sub2 (bb) {

22    line1;

23    // this line is a comment and must be ignored

24    line2;

25       sub3 (cc) {

26       line1;

27     }

28    }  

29  }

And I need to have its content converted into following format using awk or perl:

verify(abc) { foo : bar; sub1 (aa) { line1; } sub2 (bb) { line1; line2; sub3 (cc) { line1; } } }

verify(efg) { foo : bar; sub1 (aa) { line1; } sub2 (bb) { line1; line2; sub3 (cc) { line1; } } }

Many thanks in advance.

  An end of line in Unix is character n, so you just need to any (that is not alone on a line) with some preprocessing to remove any line starting with //. What did you try already?

  Removing lines starting with // is not a problem; what algorithm should I use to ensure contents of each "verify()" routine is place on one line?
