For me, strange results from a 'pipe' command
by crajor from LinuxQuestions.org on (#5CAD6)
OK so I typed this command into a terminal
[CODE]man dmesg > kmsgcmd[CODE]
Sure enough, there is now a kmsgcmd in my home directory, but this is my output from the command:

dmesg - print or control the kernel ring buffer
SSYYNNOOPPSSIISS
ddmmeessgg [options]
ddmmeessgg ----cclleeaarr

DDEESSCCRRIIPPTTIIOONN
ddmmeessgg is used to examine or control the kernel ring buffer.
The default action is to display all messages from the kernel ring buf
fer.
OOPPTTIIOONNSS
The ----cclleeaarr, ----rreeaadd--cclleeaarr, ----ccoonnssoollee--oonn, ----ccoonnssoollee--ooffff, and ----ccoonn
ssoollee--lleevveell options are mutually exclusive.
--CC, ----cclleeaarr
Clear the ring buffer.
--cc, ----rreeaadd--cclleeaarr
Clear the ring buffer after first printing its contents.
--DD, ----ccoonnssoollee--ooffff
Disable the printing of messages to the console.
--dd, ----sshhooww--ddeellttaa
Display the timestamp and the time delta spent between messages.
If used together with ----nnoottiimmee then only the time delta without
the timestamp is printed.
--EE, ----ccoonnssoollee--oonn
Enable printing messages to the console.
--ee, ----rreellttiimmee
Display the local time and the delta in human-readable format.
Be aware that conversion to the local time could be inaccurate
(see --TT for more details).
--FF, ----ffiillee _f_i_l_e
Read the syslog messages from the given _f_i_l_e. Note that --FF does
not support messages in kmsg format. The old syslog format is
supported only.
--ff, ----ffaacciilliittyy _l_i_s_t
Restrict output to the given (comma-separated) _l_i_s_t of facili
ties. For example:
ddmmeessgg ----ffaacciilliittyy==ddaaeemmoonn
will print messages from system daemons only. For all supported
facilities see the ----hheellpp output.
--HH, ----hhuummaann
Enable human-readable output. See also ----ccoolloorr, ----rreellttiimmee and
----nnooppaaggeerr.
--kk, ----kkeerrnneell
Print kernel messages.
--LL, ----ccoolloorr[=_w_h_e_n]
Colorize the output. The optional argument _w_h_e_n can be aauuttoo,
nneevveerr or aallwwaayyss. If the _w_h_e_n argument is omitted, it defaults
to aauuttoo. The colors can be disabled; for the current built-in
default see the ----hheellpp output. See also the CCOOLLOORRSS section be
low.
--ll, ----lleevveell _l_i_s_t
Restrict output to the given (comma-separated) _l_i_s_t of levels.
For example:
ddmmeessgg ----lleevveell==eerrrr,,wwaarrnn
will print error and warning messages only. For all supported
levels see the ----hheellpp output.
--nn, ----ccoonnssoollee--lleevveell _l_e_v_e_l
Set the _l_e_v_e_l at which printing of messages is done to the con
sole. The _l_e_v_e_l is a level number or abbreviation of the level
name. For all supported levels see the ----hheellpp output.
For example, --nn 11 or --nn eemmeerrgg prevents all messages, except
emergency (panic) messages, from appearing on the console. All
levels of messages are still written to _/_p_r_o_c_/_k_m_s_g, so ssyyss
llooggdd(8) can still be used to control exactly where kernel mes
sages appear. When the --nn option is used, ddmmeessgg will _n_o_t print
or clear the kernel ring buffer.
----nnooeessccaappee
The unprintable and potentially unsafe characters (e.g., broken
multi-byte sequences, terminal controlling chars, etc.) are es
caped in format \x<hex> for security reason by default. This
option disables this feature at all. It's usable for example for
debugging purpose together with ----rraaww. Be careful and don't use
it by default.
--PP, ----nnooppaaggeerr
Do not pipe output into a pager. A pager is enabled by default
for ----hhuummaann output.
--pp, ----ffoorrccee--pprreeffiixx
Add facility, level or timestamp information to each line of a
multi-line message.
--rr, ----rraaww
Print the raw message buffer, i.e., do not strip the log-level
prefixes, but all unprintable characters are still escaped (see
also ----nnooeessccaappee).
Note that the real raw format depends on the method how ddmmeessgg(1)
reads kernel messages. The /dev/kmsg device uses a different
format than ssyysslloogg(2). For backward compatibility, ddmmeessgg(1) re
turns data always in the ssyysslloogg(2) format. It is possible to
read the real raw data from /dev/kmsg by, for example, the com
mand 'dd if=/dev/kmsg iflag=nonblock'.
--SS, ----ssyysslloogg
Force ddmmeessgg to use the ssyysslloogg(2) kernel interface to read kernel
messages. The default is to use /dev/kmsg rather than ssyysslloogg(2)
since kernel 3.5.0.
--ss, ----bbuuffffeerr--ssiizzee _s_i_z_e
Use a buffer of _s_i_z_e 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.
--TT, ----ccttiimmee
Print human-readable timestamps.
BBee aawwaarree tthhaatt tthhee ttiimmeessttaammpp ccoouulldd bbee iinnaaccccuurraattee!! The ttiimmee
source used for the logs is nnoott uuppddaatteedd aafftteerr system SSUUSSPPEENNDD/RREE
SSUUMMEE. Timestamps are adjusted according to current delta be
tween boottime and monotonic clocks, this works only for mes
sages printed after last resume.
--tt, ----nnoottiimmee
Do not print kernel's timestamps.
----ttiimmee--ffoorrmmaatt _f_o_r_m_a_t
Print timestamps using the given _f_o_r_m_a_t, which can be ccttiimmee,
rreellttiimmee, ddeellttaa or iissoo. The first three formats are aliases of
the time-format-specific options. The iissoo format is a ddmmeessgg im
plementation of the ISO-8601 timestamp format. The purpose of
this format is to make the comparing of timestamps between two
systems, and any other parsing, easy. The definition of the iissoo
timestamp is: YYYY-MM-DD<T>HH:MM:SS,<microseconds><-+><timezone
offset from UTC>.
The iissoo format has the same issue as ccttiimmee: the time may be in
accurate when a system is suspended and resumed.
--uu, ----uusseerrssppaaccee
Print userspace messages.
--ww, ----ffoollllooww
Wait for new messages. This feature is supported only on sys
tems with a readable /dev/kmsg (since kernel 3.5.0).
--WW, ----ffoollllooww--nneeww
Wait and print only new messages.
--xx, ----ddeeccooddee
Decode facility and level (priority) numbers to human-readable
prefixes.
--VV, ----vveerrssiioonn
Display version information and exit.
--hh, ----hheellpp
Display help text and exit.

colorization configuration.
The logical color names supported by ddmmeessgg are:
ssuubbssyyss The message sub-system prefix (e.g., "ACPI:").
ttiimmee The message timestamp.
ttiimmeebbrreeaakk
The message timestamp in short ctime format in ----rreellttiimmee or

ddmmeessgg can fail reporting permission denied error. This is usually
