Try:

variable_after=`echo $variable_before | sed   's/\//./' `
(you must escape the "/")

If you want to replace all the occurences of "/" add an 'g' :

variable_after=`echo $variable_before | sed   's/\//./g' `


You can do this also only with bash:

variable_after=${variable_before/\//.} 

and  for multiple occurences:

variable_after=${variable_before//\//.}
