what is ^K?

[Bing Du]

Greetings,

Maybe this is not direcly Perl related...

I'm using Perl (v5.8.0) on Linux (RedHat 9) to process a text file
transferred from Windows to Unix. When I used 'vi' to open the text
file, I saw a lot ^K. In perl, how can I get rid of it? I know I can
use '$line =~ s/\r//g' to remove ^M. What about ^K?

Thanks in advance for any help,

Bing

s/\013//g

Oh, great. Thanks a lot for your instant response!

s/\013//g

That removes character with octal encoding 013. This of course is
control-K. But there is a way in Perl to say control-K more directly.

s/\cK//g;

Also I'd probably favour tr///d

tr/\cK//d;

--
\\ ( )
. _\\__[oo
.__/ \\ /\@
. l___\\
# ll l\\
###LL LL\\

tr/\cK//d;

Funny way of spelling "trAcKEd".
