I look for primary and * to isolate the interesting slot number.

Now I want to get the Touch line for only the associate slot number, in this case, because the asterisk... (2 Replies)

In the awk piped to sed below I am trying to format file by removing the odd xxxx_digits and whitespace after, then move the even xxxx_digit to the line above it and add a space between them.

renice - alter priority of running processes
SYNOPSIS
renice priority [ [ -p ] pid ... ] [ [ -g ] pgrp ... ] [ [ -u ] user ... ]
DESCRIPTION
Renice alters the scheduling priority of one or more running processes. The who parameters are interpreted as process ID's, process group
ID's, 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. By default, the processes to be
affected are specified by their process ID's. To force who parameters to be interpreted as process group ID's, a -g may be specified. To
force the who parameters to be interpreted as user names, a -u may be given. Supplying -p will reset who interpretation to be (the
default) process ID's. For example,
renice +1 987 -u daemon root -p 32
would change the priority of process ID's 987 and 32, and all processes owned by users daemon and root.
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
within the range 0 to PRIO_MAX (20). (This prevents overriding administrative fiats.) The super-user may alter the priority of any
process and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20 (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 ID's
SEE ALSO getpriority(2), setpriority(2)BUGS
Non super-users can not increase scheduling priorities of their own processes, even if they were the ones that decreased the priorities in
the first place.
