Details:

I want to grep the date string from my apache logs, but some user agents have
a bracket in them.  I need a way to grep for a string that doesn't have a ] in
it.  These are things I have tried:

[EMAIL PROTECTED]:/tmp$ echo aa [ bb ] cc ] dd | grep -o "\\[.*\\]"
[ bb ] cc ]
[EMAIL PROTECTED]:/tmp$ echo aa [ bb ] cc ] dd | grep -o "\\[^]]*\\]"
[EMAIL PROTECTED]:/tmp$ echo aa [ bb ] cc ] dd | egrep -o "\\[^]]*\\]"
[EMAIL PROTECTED]:/tmp$ echo aa [ bb ] cc ] dd | egrep -o "\\[^\\]]*\\]"
