Check numeric fields greater than zero, and delete lines if appropriate
This be the latest in my problems sorting through router logs... I'm half way there on a problem, but I've hit the limitation of my knowledge
Got some router interface log files of type
I don't care about frame errors or ignored errors, but I do want to take account of input errors, CRC errors and overrun errors, so I want to keep those lines (and the line above them) where those parameters are non zero, and I want to delete those lines where the important parameters are 0, and the lines above them. So... for the input above... I want the output to be
I'm thinking the way to do it is to sort for lines with the string "input errors", and check if the second, or fifth, or ninth parameters are non zero, and if so keep that line and the line above it, otherwise delete the line and the line above it.
I'm doing this on ubuntu... (may or may not be relevant)

Hi,
how to check the given string is numeric or not , without converting ( using strtol...).
for ex: if string is C01 - non-numeric data
if string is 001 - numeric data

Hi,
I am new to Shell scripts.
I have an urgent requirement to find the disk space using "df -k".
from that output,I need to check the used% whether greater than 85%.
if it is greater than 85% then need to delete my log files.
It is very urgent please some one help me.
Thanks in Advance... (1 Reply)

syncstat
syncstat(1M) System Administration Commands syncstat(1M)NAME
syncstat - report driver statistics from a synchronous serial link
SYNOPSIS
/usr/sbin/syncstat [-c] device [interval]
DESCRIPTION
The syncstat command reports the event statistics maintained by a synchronous serial device driver. The report may be a single snapshot of
the accumulated totals, or a series of samples showing incremental changes. Prior to these it prints the device name being used to query a
particular device driver, along with a number indicating the channel number (ppa) under control of that driver.
Event statistics are maintained by a driver for each physical channel that it supports. They are initialized to zero at the time the driver
module is loaded into the system, which may be either at boot time or when one of the driver's entry points is first called.
The device argument is the name of the serial device as it appears in the /dev directory. For example, zsh0 specifies the first on-board
serial device.
The following is a breakdown of syncstat output:
speed The line speed the device has been set to
operate at. It is the user's responsibility
to make this value correspond to the modem
clocking speed when clocking is provided by
the modem.
ipkts The total number of input packets.
opkts The total number of output packets.
undrun The number of transmitter underrun errors.
ovrrun The number of receiver overrun errors.
abort The number of aborted received frames.
crc The number of received frames with CRC
errors.
isize The average size (in bytes) of input pack-
ets.
osize The average size (in bytes) of output pack-
ets.
OPTIONS -c Clear the accumulated statistics for the device specified. This may be useful when it is not desirable to unload a particu-
lar driver, or when the driver is not capable of being unloaded.
interval syncstat samples the statistics every interval seconds and reports incremental changes. The output reports line utiliza-
tion for input and output in place of average packet sizes. These are the relationships between bytes transferred and the
baud rate, expressed as percentages. The loop repeats indefinitely, with a column heading printed every twenty lines for
convenience.
EXAMPLES
Example 1: Sample output from the syncstat command:
example# syncstat zsh0
speed ipkts opkts undrun ovrrun abort crc isize osize
9600 15716 17121 0 0 1 3 98 89
example# syncstat -c zsh0
speed ipkts opkts undrun ovrrun abort crc isize osize
9600 0 0 0 0 0 0 0 0
In the following sample output a new line of output is generated every five seconds:
example# syncstat zsh0 5
ipkts opkts undrun ovrrun abort crc iutil outil
12 10 0 0 0 0 5% 4%
22 60 0 0 0 0 3% 90%
36 14 0 0 0 1 51% 2%

bad interval: arg The argument arg is expected to be an interval and could not be understood.
device missing minor device number The name device does not end in a decimal number that can be used as a minor device number.
baud rate not set The interval option is being used and the baud rate on the device is zero. This would cause a
divide-by-zero error when computing the line utilization statistics.
WARNINGS
Underrun, overrun, frame-abort, and CRC errors have a variety of causes. Communication protocols are typically able to handle such errors
and initiate recovery of the transmission in which the error occurred. Small numbers of such errors are not a significant problem for most
protocols. However, because the overhead involved in recovering from a link error can be much greater than that of normal operation, high
error rates can greatly degrade overall link throughput. High error rates are often caused by problems in the link hardware, such as
cables, connectors, interface electronics or telephone lines. They may also be related to excessive load on the link or the supporting sys-
tem.
The percentages for input and output line utilization reported when using the interval option may occasionally be reported as slightly
greater than 100% because of inexact sampling times and differences in the accuracy between the system clock and the modem clock. If the
percentage of use greatly exceeds 100%, or never exceeds 50%, then the baud rate set for the device probably does not reflect the speed of
the modem.
