How to add string contain / character to a file in shell scripting

Question

I have a string in my .sh file

  Path="etc/name"

This I need to write into a file.

This is my File.txt

 Name:Tom

 My_Path:add path here 

 Address:Xyz

Here in this file I need to replace path by the 'path' variable in shell script.

I used

   sed -i -e "s/\(My_Path=\).*/\1$path/" file.txt

But getting error like :

   Sed: -e expression #1, unknown option to s

my desired output is , the file My_Path.txt should contain

 Name:Tom

 My_Path:"etc/name" 

 Address:Xyz

Answer 1

First escape slashes on your variable

path=$(echo $path | sed "s/\//\\\\\//g")

Then use this sed line

sed -i "s/My_Path:.*$/My_Path:$path/" file.txt

Answer 2

The issue is your Path variable also has / (forward-slash) which gets interpreted as delimiter of your sed.

So try using some other delimiter. Here i am using | as delimiter:

sed -i -e "s|\(My_Path:\).*|\1$Path|" file.txt
