Hi,
I need to do an exact find and replace (I don't want to use regular expressions because the input comes from user). I want to find a line that matches the user's input text and replace it with an empty string.
For example, let's say the user enters I love "Unix" and the contents of the file where I want to do find and replace is this:
I like "Unix" more than DOS
I love "Unix"
I said I love "Unix"
I love "Unix" a lot
Now I want to replace the line I love "Unix" with empty string. And I want to leave the remaining lines like I said I love "Unix" and I love "Unix" a lot as is. The double-quotes are intentional.
Which Unix utility can do this? An example would be great! I searched and found that sed is something close what I am looking for, but it takes a regular expression. Because the input string is coming from the user, it's tough for me to generate a regular expression for that. Any other ways?
Thanks!
