Faster way to go to a line in a file

Right now, to get to a certain line number, I will open the file, set a for loop to get a line until line number is reached, and then quit. Is there a faster way? ex: for (my $i = 1; $i = $LineNumber; $i++) { $Line = $FileHandle-getline; } Thanks. Sean --

Is there a way to get the previous line in a file?

I need a function, like getline, which gets the previous line. I'm thinking I've read somewhere how to do this, but I can't remember where. Anyone know? Sean -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Read a file directly from system call?

I think, when you use system(), that you're expecting something it's not going to give you. I found this out trying to use grep. I said my $Value = system(grep -l somevalue somefile) and the return was always 0. I found, though, that instead of using system, use the '`' character:

Where can I find the Tie module on cpan? I'm not sure where to look for. My perl distribution doesn't have it loaded, and my system administrator is gone. Sean -Original Message- From: Janek Schleicher [mailto:[EMAIL PROTECTED]] Sent: Friday, September 27, 2002 6:41 AM To: [EMAIL

I have a string that is delimited by the '|' character. I pass this string to a sub, and within the sub I break it apart using split my @Array = split(/|/, $_[1]); When I print out the array, I find that split has broken the string apart character by character, and not by the

RE: join hashes?

I know it's a reference to a hash. What I don't know is why it's printing out like this. I have hash values that I need to print out, but not in any order, so I put each hash value that I want to print in a join statement in the order I need them. The really strange part is that I also have a

RE: getppid?

I'm having a very strange problem that I'm hoping someone has come across before. I'm using a hash to collect some field values. I want to write the hash values to file, and I want them delimited by the '|' character, so I use my $LineToWrite = join('|', hash_var_1, ..., hash_var_n) .
