Using a variable with sed in a Script shell

Question

I am writing a shell script for editing Modify Aegis Attributes. command i use:

aegis -Change_Attributes -Edit

which opens the vi editor for transferring outside of the changes. I want to do a search and replace:

s/brief_description \= \"none\"\;/brief_description \=

\ "test \" / g

Can I pass them directly to open vi through a script without typing in any of them? I want to save a document (: wq) after editing it.

PS The file is a temporary file created when the command is executed, so I do not know the original path

Edit: I could use sed in this case:

sed -e 's/brief_description\ \=\ \"none\"\;/brief_description\ \=\

\ "test \" \; / g '

Solution (inelegant hack?) To be a "cat" exit from the aegis (setenv VISUAL cat), make changes place the stream with the specified command and save it in a temporary file and use:

aegis -change_attributes -file <temp file>

EDIT2: . , sed

script:

sed -i 's/brief_description\ \=\ \"none\"\;/brief_description\ \=\ \"${DESC}\"\;/g' temp_next.txt

$DESC , out put :

brief_description = "$ {DESC}";

DESC sed, ?

EDIT3:

sed -i 's%brief_description\ \=\ \"none\"\;%brief_description\ \=\ \"'"$DESC"'\"\;%g' temp_next.txt
