Dotan, Keep in mind that he is EXCLUDING lines that have those two values, so in this case, the use of '|' (OR) gets the desired result. A line cannot have either value, which is the same as saying that a line cannot have both values.
I manned the -v option after posting. Sorry. I'm still a bit close to the X axis on the learning curve.
If he wanted lines that INCLUDED both values, then the approach would require the piped double grep approach,
That's what I thought he was doing. Until I manned -v.
One approach, for example, might be to use a Perl based Regex, with Lookahead. This one will return lines in .Xresources that have BOTH 'xterm' AND 'white' in them: $ grep -P "(?=.*xterm)(?=.*white)" .Xresources xterm*background: white
My god, that's scary.
or return lines that have BOTH 'default' AND 'ground': $ grep -P "(?=.*default)(?=.*ground)" .Xresources Emacs.default.attributeBackground: white Emacs.default.attributeForeground: black XEmacs*EmacsFrame.default.attributeForeground: black XEmacs*EmacsFrame.default.attributeBackground: white
Agh! Stop!
In this way, we can combine multiple regex's in a single grep call.
I'll just continue double grepping, until I fully explore Beagle. Thanks. Dotan Cohen http://technology-sleuth.com/long_answer/how_can_i_be_safe_online.html http://what-is-what.com/what_is/microsoft_windows.html
