The tail command is one I am sure many people use every day in Linux, both sysadmins and users, but I do believe there are options that are often overlooked. This holds true with many commands and options. That said, the road less trodden, is usually less trodden for a reason. On occasion however, we come across options that are perfect. This is the case with the –pid option in tail. We can follow a file until a process end.
In this video man page for Linux we take you though this an other option for the command tail…enjoy.
