in reply to Uer Perl Variable in txt file

I don't feel that I understand what you are getting, based on the snippet of source code that I see ... but here is one important thing to keep in mind: the difference between single and double quotes.

A string such as 'This is $name' will be output literally as it appears, whereas a string in double quotes such as "This is $name" will have the variable-name interpolated.   That is, if $name is Fred, you get:   This is Fred in the second case but not the first.

    I have a file which has contents like this

    ______file.txt_______
    I am $name
    I am from $city
    I live $food
    I got $car


    Using perl code I am reading line one by one from file.txt. When I print line using $_ it does not replace variable in text file with variable values in .pl file but it prints the line as it is.
