  15. interactive feedback to the user. Here is a copy of my code:
  16.  
  17. CSHRC=/tmp/cshrc
  18.  
  19. string="`grep $1 ${CSHRC}`"
  20.  
  21. if [ -z "$string" ]
  22. then
  23. echo "setenv $1 $2" >> ${CSHRC}
  24.  
  25. else
  26. ex - | -s  ${CSHRC}  <<-end_of_edit
  27. /setenv *$1
  28. d
  29. i
  30. setenv $1 $2
  31. .
  32. w
  33. q
  34. end_of_edit
  35.  
  36. fi
  37.
