sys-utils: move some man pages from category 8 to 1
The dmesg, ipcrm, ipcs, renice and setsid are user-accessible commands
and belong in man1 more than to man8.

Instead of +copying the messages by hand, the user need only: +.RS +dmesg > boot.messages +.RE +and mail the +.I boot.messages +file to whoever can debug their problem. +.SH OPTIONS +.TP +.B \-c +Clear the ring buffer contents after printing. +.TP +.BI \-s bufsize +Use a buffer of size +.I bufsize +to query the kernel ring buffer. This is 16392 by default. +(The default kernel syslog buffer size was 4096 +at first, 8192 since 1.3.54, 16384 since 2.1.113.) +If you have set the kernel buffer to be larger than the default +then this option can be used to view the entire buffer. +.TP +.BI \-n level +Set the +.I level +at which logging of messages is done to the console. For example, +.B \-n 1 +prevents all messages, expect panic messages, from appearing on the +console. All levels of messages are still written to +.IR /proc/kmsg , +so +.BR syslogd (8) +can still be used to control exactly where kernel messages appear. When +the +.B \-n +option is used, +.B dmesg +will +.I not +print or clear the kernel ring buffer. + +When both options are used, only the last option on the command line will +have an effect. +.SH SEE ALSO +.BR syslogd (8) +.\" .SH AUTHOR +.\" Theodore Ts'o (tytso@athena.mit.edu) |
