Re: [SLUG] perl substitution of metacharacter

["Stuart Cooper" <stucoope@xxxxxxxxx>]

Hi Rachel,

   I have a little problem that I don't seem to be able to nut 
   out. 

   I have a file that's being processed by Perl that has a bunch of 
   "^@" symbols in it.   This is the "Control-at" character. 

It's more than that, it's the NUL character, chr(0). ^A is chr(1), ^B
is chr(2)... through to ^Z = chr(26), before that you get ^@ which is
chr(0). See the top of man ascii.

   I want to expunge the file of all the "^@" symbols.

My entry in the "neat one liner" competition to do this is:
$ perl -p -i -e "s/\000//g" infile

in the days before Perl you would use sed to do it.

Regards,
Stuart.
