Add characters to the end of a string using regex notepad2

问题

I have a massive string (a SQL query..) that I have written out in notepad2. I'm using Java, and I was just wondering if there was a fast and easy way to add something to the end of each line? For example:

String query = "" 
+ " select column1
+ " , column2
+ " , column3
+ " from table
);
//want to add \n" at the end of each line

回答1:

Find: (.)$
Replace: \1\\n"

Here's a good regex tutorial.

回答2:

Maybe something like this

1. ctrl + H
2. mark regular expressions option
3. search for $ - this means "end of line"
4. replace with \\n"

OR simpler

1. select lines that you want to edit
2. alt + M / same as edit->block->modify lines
3. in append text to lines place \n"

For anyone still here 5 years later, and you are attempting to add something onto the end a line for a large non-code file (and don't want to use REGEX), there are helpful online converter tools like https://pinetools.com/add-text-each-line.

Helped me out a bunch for creating CSV files for a neural network I was making

回答4:

ctrl+h

make sure regex is on.

find: (.)\r\n

replace: \1 + "\\\n"\r\n

回答5:

In Regex you can group expressions using () - Parenthesis, and represent them as \1, \2, etc. So, anything like this can be appended as follows:

Find: (.*); Replace: \1 your_new_text ;
