Re: Delete a line from files

Further to AnonyMonk's advice above, also consult perlrun about the effects of the -i, -n and -l flags; they all act to add code around the code you supply on the command line.

Update: E.g.,

c:\@Work\Perl\monks>perl  -MO=Deparse,-p  -i -n -le
"/apple/||print
"
BEGIN { $^I = ""; }
BEGIN { $/ = "\n"; $\ = "\n"; }
LINE: while (defined(($_ = <ARGV>))) {
    chomp($_);
    (/apple/ or print($_));
}
-e syntax OK
