Just to show that several regexes can achieve the same S/R, here is a second solution :

• Open your file in Notepad++

• Open the Replace dialog ( CTRL + H )

• In the Find what: field, type in @(?:.+?)(?=:)

• Leave the Replace with: EMPTY

• Select the Regular expression search mode

• Finally, click on the Replace All button

Et voilà !

NOTES :

• This regex looks, first, for the literal character @.

• At the end of the regex, the part (?=:), called a look-ahead, is a condition, that means that the overall match must be followed by a literal colon :.

• So, the inner middle part, .+?, tries to match the shortest range of any character between the @ character, included and the : character, excluded.

• The symbol + is a quantifier that means a maximum of characters, from 1 to n and the symbol ?, after the quantifier +, forces the regex engine to select the minimum range of any character, between the limits @ and :

• As this range of characters is included in the syntax (?: .... ), this means that the range, of each line, will NOT be stored for later use, either in the Find or Replace regexes.

• Finally, as the Replace dialog is empty, this range is just deleted, from each line !

Beware : if you prefer to use the abelfourier’s search regex, the correct regex is, obviously :

@(?:[^.]+)\.COM

You’ll have to uncheck the Match case option
