Re: regex, negations, grep, find and replace (a few questions)

Use -o (man grep). For the multi-line problem, just remove the
newline characters before piping the text to grep, eg

echo $text | tr -d '\n' | grep 'your_pattern'

that is really interesting, thanks..
that -o is ideal (and that tr command also shows me how to convert
windows-->unix , since it just involves removing the CR '\r')
note- that command would return all $text or all the file, since you
missed the -o from grep. But I only know about -o since you mentioned
it! I think you intended to include it.

Of course, it escaped me. The -o has the added benefit that if multiple occurrences of the pattern occur in the same line, grep outputs them separately, eg

$ echo "helloblahhello" | grep -o hello
hello
hello

I actually dealt with this find/replace or extraction problem by using
the regex I mentioned, but with grep -o , making a new file.
Then, since it was intented html code I used an old feature of MS Word,
which is probably in linux`s Open Office too. I made the font Courier
(a fixed width font). I held ALT and highlighted in a rectangle, what
I wanted to select, and removed characters i did not want from each
link in one go. I made the font size tiny and the zoom high, to
remove wordwrap.

With OO you can do search/replaces using regexes, something that office cannot do (and won't likely do in the future either, imho).
