How do I add a number at the end of every line in Notepad++?

How do I add a number at the end of every line in Notepad++?

• Menu "Search" > "Replace" (or Ctrl + H)

• Set "Find what" to \r\n

• Set "Replace with" to 1\r\n

• Enable "Regular expression" or "Extended"

  Note - "Regular expression" is a superset of "Extended" so in this particular case it doesn't matter which one you use.

• Click "Replace All"

Notes:

• The above assumes you are editing a text file with Windows EOLs, \r\n.

• If you are using files with different EOLs you can convert them to Windows EOLs using Menu "Edit" > "EOL Conversion".

• If you aren't working with Windows EOL, and you don't wish to convert them, use the following instead:

  • Use \n instead of \r\n for Unix/OS X EOLs ("Find what" is \n, "Replace with" is 1\n)

  • Use \r instead of \r\n for Mac OS (up to version 9) EOLs ("Find what" is \r, "Replace with" is 1\r)

Replace with: 1

And hit Replace all

Original answer

Hit Ctrl + H for opening the Replace Dialog.

Under search mode, tick Regular Expression.

Find what: ^.*$

Replace with ($0)1

And hit Replace all

Explanation

You are searching for the regular expression ^.*$, which is esentially every line. ^ marks the beginning of a line, .* includes any character any number of times and $ marks the end of the line. Thus, this regular expression finds all content on every line.

We replace this expression with ($0)1, $0 being the found expression, and appending a 1 to it.

Solution 4:

Or do it like the big boys do :).

Select the last column using Shift + Alt => right key (once) => down key (press till the last line).

Type whatever you want. It will appear on all lines at once.
