Open file from another machine

[CristianLuca]

Hello again,
What is the most efficient way to open a file through network ? Considering that i'm writting a cron that from 10 to 10 minutes logs on several machines [1-10] and gets some log
file. ( like 16-265 log files per machine )

Thank you in advance,
Cristian

There is probably isn't that much difference between the different options that are probably available to you.

FTP/RCP/SCP. We move massive amounts of data around using FTP and SCP.

Thanks, i do not know how to open a file through network, so i was wondering what was the best way to do that.

Oh.. I was assuming you were copying it back and opening it. Are you trying to grep through the logs or something?

this is my logic :

foreach machineName (machineNames) { # $# machineNames = [0-15]
foreach fileName (fileNames) # $#fileNames = [0-255]
open(machineName::FH,>$fileName)
#read something from machine::FH
}
}

i could just simply copy the file to my machine using scp, but that's useless , since i'm just looking for greping the last input rom each file

Why not do it the other way around? Write a script that takes the last line from each file that runs on the same machine the files are located on. Then transfer the result to wherever you're centrally processing them via SCP.

Assuming you are on a UNIX/Linux machine. You can try the tail command using ssh:

ssh hostname tail -1 /path/to/file

Note: You will have to add public key to your environments for scripting functionality.
