Hey Markus,

Currently there is no way to do that directly with BBEdit.

Please make a feature request to support: Bare Bones Software <sup...@barebones.com>

The more of us who do the more likely they'll listen.

Personally I think the inversion switch should be included in the Process Duplicate Lines dialog, but I made my formal request some time ago.

In the meantime it's pretty easy to roll-your-own:

------------------------------------------------------------------------------------------------

try

  

  tell application "BBEdit"

    tell me to set ddStr to text returned of (display dialog "Enter grep pattern:" default answer "" giving up after 120)

    if ddStr ≠ "" then

      set _text to quoted form of (get text of front text window)

      set shellCMD to "echo " & _text & " | tr '\\r' '\\n' | egrep -iv " & "\"" & ddStr & "\""

      set filteredText to do shell script shellCMD

      make new text document with properties {text:filteredText}

    end if

  end tell

  

on error eMsg number eNum

  set {c, s} to {return, "------------------------------------------"}

  set e to s & c & "Error: " & eMsg & c & s & c & "Error Number: " & eNum & c & s

  beep

  set dDlg to display dialog e buttons {"Cancel", "Copy", "OK"} default button "OK"

  if button returned of dDlg = "Copy" then

    set the clipboard to e

  end if

end try

------------------------------------------------------------------------------------------------

I've got case-sensitive set OFF in the script.

Process lines containing, and copy the lines that do contain the certain pattern into a new file, or use the clipboard as an intermediate.

This GREP pattern can be used to delete lines which don't begin with 'save', but I don't know enough about negative lookahead assertions to know if it can be changed to look anywhere in the line:

^(?!save)

English is not my first language. I try to keep it short but I don't want to sound unfriendly.

If you have a file (MyFile):

George Smily, Modesty Blaise, Olof
Karla, Willy Garvin, Zorro
George Smily, Modesty Blaise, Karla
Olof, Karla, Willy Garvin, Zorro

Try a shellscript like:

egrep -v 'Olof' Path-to-MyFile | bbedit

This will exclude all lines containing 'Olof' and you will have:

Karla Willy Garvin Zorro
George Smily, Modesty Blaise, Karla

in a new document in BBedit.
