Hi,
When I do a man and save it into a file, I end up getting a lot of control characters. How can I remove them??
I tried this:
/1,$ s/^H//g
But I get an error saying "no previous regular expression".
Can someone help me with this.
Thanks,

LEARN ABOUT NETBSD
schedctl
SCHEDCTL(8) BSD System Manager's Manual SCHEDCTL(8)NAME
schedctl -- control scheduling of processes and threads
SYNOPSIS
schedctl [-A cpus] [-C class] [-P pri] [-t lid] -p pid | command
DESCRIPTION
The schedctl command can be used to control the scheduling of processes and threads. It also returns information about the current schedul-
ing parameters of the process or thread. Only the super-user may change the scheduling parameters. schedctl can also be used to start a new
command using the specified parameters.
Available options:
-A cpus Set of the processors on which process or thread should run, that is, affinity. Processors are defined as numbers (starting from
zero) and separated by commas. A value of -1 is used to unset the affinity.
-C class Scheduling class (policy), one of:
SCHED_OTHER Time-sharing (TS) scheduling policy. The default policy in NetBSD.
SCHED_FIFO First in, first out (FIFO) scheduling policy.
SCHED_RR Round-robin scheduling policy.
-P pri Priority for the process or thread. Value should be in the range from SCHED_PRI_MIN (0) to SCHED_PRI_MAX (63). Setting of prior-
ity for the process or thread running at SCHED_OTHER policy is not allowed.
-p pid The target process which will be affected. If the process has more than one thread, all of them will be affected.
If -p is not given, a command to execute must be given on the command line.
-t lid Thread in the specified process. If specified, only this thread in the process will be affected. May only be specified if -p is
also given.
EXAMPLES
Show scheduling information about the process whose ID is ``123'':
# schedctl -p 123
Set the affinity to CPU 0 and CPU 1, policy to SCHED_RR, and priority to 63 for thread whose ID is ``1'' in process whose ID is ``123'':
# schedctl -p 123 -t 1 -A 0,1 -C SCHED_RR -P 63
Run the top(1) command with real-time priority:
# schedctl -C SCHED_FIFO top

The schedctl command first appeared in NetBSD 5.0.
