This is the command mlock that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
mlock -- lock a mailbox
SYNOPSIS
/usr/bin/mlock
DESCRIPTION
If libc-client.so is unable to create a mailbox lock file, it will call this program.
This makes using the mailbox safe over i.e. NFS. There is no reason to call mlock yourself
or through another program. It is setgid mail so there is no need to change the
permissions of /var/mail to 1777.
Use mlock online using onworks.net services
