How to use sed to replace string with backtick

How to I can use, shell/bash script's 'sed', to replace string with content of variable and surround it by acute/backslash.

For example:

file (file.txt) containing line

FILE_PATH="this/is/the/file/path"

to be replaced like

FILE_PATH=`get/file/path/get.sh FILE_NAM`

I tried the following sed, but did not work for me

SCRIPT_PATH="get/file/path/get.sh FILE_NAM"
sed -i "s,\"this/is/the/file/path\",`$SCRIPT_PATH`,g" $file

above resulted

FILE_PATH=get/file/path/

but expected is

FILE_PATH=`get/file/path/get.sh FILE_NAM`

Can someone please help me to get replace string with content of a variable with acure around value of variable.

If the issue is purely with sed, your command isn't formatted quite correctly. It looks like the overall issue is you aren't printing the escape sequence for the ` character, which is a special character in bash for executing shell commands within another command.

Based on your desired results and sample code, the following works for me in bash.

SCRIPT_PATH="this/is/the/file/path"
sed -i "s|\"this/is/the/file/path\"|\`$SCRIPT_PATH\`|g" file.txt

I found the answer as below:

SCRIPT_PATH="get/file/path/get.sh FILE_NAM"
sed -i "s,\"this/is/the/file/path\","\`"$SCRIPT_PATH"\`",g" $file
