Hello all,
I've only been using perl for about 3 months now, so be gentle with me.
I'm trying to remove a section of a certain line in a file.
Code:
use warnings;
$file = $ARGV[0];
open (FILE,$file) or die "Can't open $file!";
while (<FILE>) {
$line = $_;
chomp $line;
if ($line =~ /\>/) {
@modify_line = split(/\s/,$line);
$changed_line = shift(@modify_line);
$line=$changed_line;
print "$line\n";
}
}
close FILE;
The code is working in that the desired section of the line is removed, but the file itself remains unaffected. The result is merely printed to the screen.
How do I get the result to change the line in the file itself, not just print to the screen?
