Grep find multiple instances of string in same line?

[David Brostoff]

Easy, I think (although not for me):

How can I find lines with more than one instance of "@" or ".com"?

Thank you,

David

Hey David,

Simple:

^.*@.*@.*

A little more complicated (reusing the first found “@” via a capture).

^.*(@).*\1.*

Simple:

^.*\.com.*\.com.*

A little more complicated (reusing the first found “\.com” via a capture).

^.*(\.com).*\1.*

Thank you very much--these work great.

By the way, what does the "^" represent?

In the tutorial I found, it says, "beginning of line."

I meant to include the URL for the tutorial:
<https://www.anybrowser.org/bbedit/grep.html#star1>

Maybe there is a better one?

Hey David,

That's the caret character, and you're exactly right.

Here's my regex cheat sheet for BBEdit and TextWrangler:

To match such lines separately, please see the patterns in Chris
Stone's prior post.

To find both types of line concurrently, please try this:

^.*(@|\.com).*\1.*$



[PS: I recommend always including an end-of-line specifier $ in
patterns which one intends to make line-based matches.]

Since the above page is very old and no longer entirely
accurate, I recommend you instead refer to Chapter 8 "Searching
with Grep" in the included PDF manual (just choose Help -> User
Manual), and/or you may also find Chris's cheat-sheet helpful. :-)

One of the reasons I wrote the cheat-sheet is so I could open it in BBEdit (or TextWrangler) and search it.  :)

tell application "TextWrangler"

  set twApp to a reference to it

  tell document "RegEx Cheat Sheet.txt"

    if it exists then

      if index of its window ≠ 1 then

        set index of its window to 1

      end if

    else

      tell twApp to open bbeditCheatSheetPath opening in new_window

    end if

    if bounds of its window ≠ preferredWindowBounds then

      set bounds of its window to preferredWindowBounds

    end if

  end tell

end tell

I have this AppleScript bound to Cmd-Opt-Ctrl-G for quick access.

Of course the cheat-sheet must exist and reside at the path given in bbeditCheatSheetPath.

preferredWindowBounds is my preference, but you can easily change it to suit.
