  14. Question... (not to sound like a party pooper here,
  15. its a very nifty script). Why arent you trapping interupts
  16. like SIGINT (CONTROL+C)? It would really help your script...
  17.  
  18. Here's an example:
  19.  
  20. #!/bin/sh -e
  21.  
  22. <<COMMENT

  24. error-level table:
  25.  
  26. 0     Normal
  27. 1     SIGHUP
  28. 2     SIGINT
  29. 15    SIGTERM
  30.  
  31. COMMENT

  33. trap 'graceful_exit' 1 2 15
  34.  
  35. graceful_exit() {
  36.  
  37.   echo  'put cleanup routines here...'
  38.   exit 1
  39.  
  40. }
  41.  
  42. echo 'invoke control+c for example'
  43.  
  44. sleep 10
  45.  
  46. echo 'script exited normally'
  47.  
  48. # eof
