Re: How can I find and delete a line from a file?

Put simply, you'll have to read in the file, process it, and then save it back out.


my( $filename, $arg1, $arg2 ) = @ARGV;

open IN, '<', $filename or die;
my @contents = <IN>;
close IN;

@contents = grep !/^$arg1,$arg2,/, @contents;

open OUT, '>', $filename or die;
print OUT @contents;
close OUT;

This will force the first and second field in the file to match exactly the first and second arguments that you pass in.

If you know the exact line number you want to "delete," try this one-liner: `perl -ni -e "print unless $. == $linenum" <filename>`	[reply] [d/l]
