why “extra characters after command” error shown for the sed command line shown?

Question

I have given the command line as shown below,

command:

sed \'/dump 0 $2 $3 $4 $5/dump 1 $2 $3 $4 $5/g\' base_file.properties

error

Answer 1

It appears that some of the variables are expanding to values that contain a /. Use a different delimiter that isn't contained in any of the variables, e.g.

sed 's@dump 0 $2 $3 $4 $5@dump 1 $2 $3 $4 $5@g' base_file.properties

(Your first command isn't a valid sed expression.)
