eli(8) System Manager's Manual eli(8)
Name
eli - error log initialization program
Syntax
eli [ options ]
Description
The command initializes error logging. This command enables error logging of hardware and system-related error packets, or error messages,
from the kernel errorlog buffer. It can also disable error logging, reconfigure error logging parameters, or initialize the kernel error-
log buffer.
Options
-d Disables error logging.
-e Enables error logging in multiuser mode.
-f Forces the subsequent option; the system will not prompt. This is the only command option you can use with another option.
-h Prints information about the command.
-i Initializes the kernel errorlog buffer. The previous contents of the errorlog buffer are lost.
-l Logs a one-line status message to the kernel errorlog buffer.
-n Only supported for local error logging. Disables logging error packets to disk by the daemon. High priority error messages continue
to be printed at the console. Note that error log packets can be viewed by using the option in real time, but are never written to
the disk. For this reason, this option is rarely used.
-q Suppresses the periodic display, on the console, of the missed error message that results from a full kernel errorlog buffer.
-r Reconfigures error logging. Use this option after changing the file.
-s Enables error logging in single-user mode.
-w Enables the missed error message to appear on the console every 15 minutes. This option is the opposite of
Examples
This example logs a one-line message into the errorlog file.
eli -f -l "This is a test message"
This example logs a message, up to and including the first new line, from the file
eli -f -l < myfile > /dev/null
Restrictions
You must have superuser privileges to use the command.
Only the -f option can be used with other options. You must use the syntax shown in the examples above.
Diagnostics
eli: Request Aborted.
The requested action was aborted. The reason for the aborted command is included with the output.
