As root, I want to create a directory and set the group and ownership permissions at the same time with one command, instead of making the directory, then going back and doing a chown and chgrp.
I don't see an option for this in the mkdir man page. Would I pipe chown and chgrp with my... (1 Reply)

renice
RENICE(1) User Commands RENICE(1)NAME
renice - alter priority of running processes
SYNOPSIS
renice [-n] priority [-g|-p|-u] identifier...
DESCRIPTION
renice alters the scheduling priority of one or more running processes. The first argument is the priority value to be used. The other
arguments are interpreted as process IDs (by default), process group IDs, user IDs, or user names. renice'ing a process group causes all
processes in the process group to have their scheduling priority altered. renice'ing a user causes all processes owned by the user to have
their scheduling priority altered.
OPTIONS -n, --priority priority
Specify the scheduling priority to be used for the process, process group, or user. Use of the option -n or --priority is optional,
but when used it must be the first argument.
-g, --pgrp
Interpret the succeeding arguments as process group IDs.
-p, --pid
Interpret the succeeding arguments as process IDs (the default).
-u, --user
Interpret the succeeding arguments as usernames or UIDs.
-V, --version
Display version information and exit.
-h, --help
Display help text and exit.
EXAMPLES
The following command would change the priority of the processes with PIDs 987 and 32, plus all processes owned by the users daemon and
root:
renice +1 987 -u daemon root -p 32
NOTES
Users other than the superuser may only alter the priority of processes they own. Furthermore, an unprivileged user can only increase the
``nice value'' (i.e., choose a lower priority) and such changes are irreversible unless (since Linux 2.6.12) the user has a suitable
``nice'' resource limit (see ulimit(1) and getrlimit(2)).
The superuser may alter the priority of any process and set the priority to any value in the range -20 to 19. Useful priorities are: 19
(the affected processes will run only when nothing else in the system wants to), 0 (the ``base'' scheduling priority), anything negative
(to make things go very fast).
FILES
/etc/passwd
to map user names to user IDs
