Using the watch command, is there a way to echo the output to a logfile?
I run root-tail on my desktop and would like to see the result show up their.
Generically speaking, what is the bash script syntax that will echo any output that normally wouldn't be displayed--I know it's broad and vague, sorry.
Lastly, does anyone know which logfile has the unix/linux system main console? If I'm not mistaken doesn't every application echo something somewhere? E.g. when you launch say firefox from the bash prompt you all kinds of output, isn't this and all aps echo some kind of content to a "core" log file?
I'm sure I'm doing something wrong but as I am new to bash shell scripting I'm not sure what:

This is the command. Assume file1 exists but file2 does not:
ls file1 file2 >newfile 2>&1

I have a text file called file1 which contains the text: "ls -l"
When I enter this command:

file1 gets erased. However if I enter this command:

the output from "ls -l" is stored in newfile. My question is why doesn't file1's text ("ls -l") get... (3 Replies)

bootlogd
BOOTLOGD(8) Linux System Administrator's Manual BOOTLOGD(8)NAME
bootlogd - record boot messages
SYNOPSIS
/sbin/bootlogd [-c] [-d] [-r] [-s] [-v] [ -l logfile ] [ -p pidfile ]
DESCRIPTION
Bootlogd runs in the background and copies all strings sent to the /dev/console device to a logfile. If the logfile is not accessible, the
messages will be kept in memory until it is.
OPTIONS -d Do not fork and run in the background.
-c Attempt to write to the logfile even if it does not yet exist. Without this option, bootlogd will wait for the logfile to appear
before attempting to write to it. This behavior prevents bootlogd from creating logfiles under mount points.
-r If there is an existing logfile called logfile rename it to logfile~ unless logfile~ already exists.
-s Ensure that the data is written to the file after each line by calling fdatasync(3). This will slow down a fsck(8) process running
in parallel.
-v Show version.
-l logfile
Log to this logfile. The default is /var/log/boot.
-p pidfile
Put process-id in this file. The default is no pidfile.
BUGS
Bootlogd works by redirecting the console output from the console device. (Consequently bootlogd requires PTY support in the kernel con-
figuration.) It copies that output to the real console device and to a log file. There is no standard way of ascertaining the real con-
sole device if you have a new-style /dev/console device (major 5, minor 1) so bootlogd parses the kernel command line looking for con-
sole=... lines and deduces the real console device from that. If that syntax is ever changed by the kernel, or a console type is used that
bootlogd does not know about then bootlogd will not work.
