Re: Question about reading specific line in a text file

[nagalenoj]

Try this..,

open (DATAFILE3, $prog);
@lines = <DATAFILE3>;
close(DATAFILE3);

$lines[76] =~ s/^(\S+\s+\S+).*/$1/;
print "$lines[76]><br>\n"

Also, it is not a good practice to read the entire file in a single attempt. Think, what happens if the file is huge in size?

Try something like this to avoid reading the file like the above

open (DATAFILE3, $prog);
while (<DATAFILE3>) {
     next if 1 .. 75; # flip-flop operator
     $line = $_;
     last;
}
# $line has the 76th line, do your stuff now.

close(DATAFILE3);

Actually, you only need one control statement if you know exactly the line number you want to process, by using $. aka $INPUT_LINE_NUMBER in English.

while (<DATAFILE3>) {
     $line = $_, last
        if $. == 76;
}
