Hi!
I have a file like:
--/tmp/test---
^
word1 ^ word2
word1 ^word2 word3
word1 word2^ word3
----
If I want to grep out all lines with a single '^' character as a word, I say
grep '\b\^\b' /tmp/test
but it does not give back the first two lines of the file, as expected.
However
grep '\B\^\B' /tmp/test
archive good results. The same thing happends if I use '$' instead of '^'.
Is it a bug of a ''feature''. I did not find any explanation of this on
the web.
Thanks in advance,
Attila
