This can fool the VM into thinking that these are really executables, and will not engage priority paging on these files. - some new commands like plimit(1): Set or get resource limits of a process by taking a process ID (PID) as an argument (limit and ulimit only work with the current process) pgrep(1): Find a process by name and print the PID pkill(1): Find a process by name and send it a signal specified on the command line traceroute - File Access Control Lists "facls" (man setfacl) added with Solaris 2.5.1 are damn usefull. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu Please read the FAQ at http://www.tux.org/lkml/
