How do I remove lines of text before this character?

Question

Let's say I have this little text file, for example reasons.

[email protected]:948
[email protected]:11111===
[email protected]:123

How would I remove all the text before ===?

I use Windows 10 so no need for anything about Linux.

Solution

• Ctrl+H
• Find what: ^.*(?====)
• Replace with: LEAVE EMPTY
• check Wrap around
• check Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

^           # beginning of line
  .*        # 0 or more any character but newline
  (?=       # positive lookahead, make sure we have after:
    ===     # 3 equal sign
  )         # end lookahead

Result for given example:

[email protected]:948
===
[email protected]:123

A general FYI that's off-topic, but wanted to share from my own experience: You may want to look at VS Code in lieu of Notepad++ for a variety of reasons, but mainly due to Notepad++ having almost non-existent community development, lack of themes and true dark theme support, a myriad of untrusted plugins, etc.

VS Code is arguably overkill for general text editing, especially since it can be extremely resource intensive for what should be simple, low-cost operations like text replacement/removal.

i have a newer version of np++, how do i change the direction?

[lakshman]

what is the version you are using?

[chalbrak]

7.7.1, i'm not sure what to do

[lakshman]

If it has backward direction checkbox, untick it

[chalbrak]

i unchecked backward direction, copy and pasted everything, left replace with empty, put in your code in the find what section, used regular expression and selected the space before the first character and nothing happened

[chalbrak]

thanks, but i also wanted it to be that it removes all of the text before it (including the previous lines eg. thisisanexample)

@Your question wasn't clear. Change Find what: \A.*(?====) and Check . matches newline. Ths will remove ALL lines from the beginning of the file until === If this doesn't work as expected, please, edit your question and add sample lines and expected result.
