Question need help in forking

I have an input file with contents like:
5785690|68690|898809
7960789|89709|789789
7669900|87865|659708
7869098|65769|347658

so on..

I need to pass this file to 10 parallely running processes (forking)so that each line is processed by a process and no line is processed twice and write the output to a single output file with out ant collision between processes.
Can any one help me out in this:-(

NAME
systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path - Query the user for system passwords on the console and via wall SYNOPSIS
systemd-ask-password-console.service systemd-ask-password-console.path systemd-ask-password-wall.service systemd-ask-password-wall.path DESCRIPTION
systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for boot. systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is intended to be used after boot to ensure that users are properly notified. See the developer documentation[1] for more information about the system password logic. Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line parameters. SEE ALSO
systemd(1), systemd-tty-ask-password-agent(1), wall(1) NOTES
