What does the following code do? The result of command `cleartool ...` is ("ACPT").

Code

   
 
$cmd = `cleartool desc -fmt %[ENV]Sa stream:TCI_ACPT@\TCI_PVOB`;  
 
$cmd =~ /.+\"(.+)\"/;

It looks at the contents of the $cmd variable, captures whatever is inside the double quotes and stores the value into the $1 special variable.

The following should print ACPT:

Code

print $1;
