Hello,
2010/4/11 Chris Watkins <chriswaterguy(a)appropedia.org>rg>:
This is as more about the learning process than the
actual task... but I
can't see what's wrong with my regex, and I'd appreciate any pointers.
I want to find cases where a header is not followed by a line break, e.g.
"== External links ==;http://www.americanbamboo.org/GeneralInfo.html
I tried various regex strings, including "([\r\n]==[^\n=]*==)([^=\r ])"
(allowing for the fact that excess spaces on the end aren't important) to
be replaced by "\\1\n\\2"
But I get many false matches. See
http://www.pastie.org/913753 for details
of the good and the false matches.
In #regex on freenode I was told to try:
"s/((={2,}).*?\2)(?!\n)([^=]?)/\1\n\2/g" but it gives the error: "bash:
!\n:
event not found".
Regarding this particular issue, you should read
http://mywiki.wooledge.org/BashPitfalls#echo_.22Hello_World.21.22
Using single quotes instead of double quotes should work. Or just put
"set +o histexpand" in your .bashrc ...
I'm told that it works -
http://pastie.org/913765 - but in my terminal I
can't get past the bash error.
Thanks!
