Using a variable inside Sed expression for the command

Question

I'm trying to change few things in a file based on line numbers.

sed -n -i "$command|ABC|XYZ" ".$file_name"

The command variable is going to take the values such as 200s,311s and so on

I'm getting "sed: -e expression #1, char 32: unterminated `s' command"

What could be going wrong?

you can try this;

sed -i "$command|ABC|XYZ|" ".$file_name"

you need to insert | after XYZ and delete -n option.

Why change ".$file_name" for ${file_name} ? The OP may want to apply command on hidden file and filename should be quoted.

Thanks muzido and Kenavoz. It started working after the suggested change
