From the above file, I want to develop a shell script that extract all lines lines from the above log file from the position onwards last time it executed(The last execution time will be recorded). For instance the log file may have thousands of line; the intention is to run the shell script as cronjob with a frequency of 15 minutes. So when the first time cronjob runs it will read all the files and the subsequent execution it needs to extract the lines of log entries from and after the time of script execution.
Having said the above requirement; I am looking for one piece of information here in this forum. I can get the execution time of the script in time format lets say using "date '+%T'". For example if I am executing script (cronjob) in the time of 19:00:00; then extract all the lines using grep that has entries after logged in 19:00:00 .I can have a logic of reading the log file line by line by incorporating a logic of incrementing execution time. However I suspect that may make the operation expensive if the log file has too many entries. So I am looking for a logic that is competitively less expensive operation. Any advice in this regards would be great help.
Thanks in advance,
Rijesh.

I need to extract the date part from the file name (20080221 in this ex) and compare it with the current date and delete it, if it is a past date.
$file = exp_ABCD4_T-2584780_upto_20080221.dmp.Z
really appreciate any help.

You are given a 1 year logfile with each line starting with a date in the form “YYYY-MM-DD”. How would you extract logs from the 4th day of each month and put them into a new file (1 Reply)
Hello,
I have a log file for the year, which contains lines starting with the data in the format of YYYY-MM-DD. I need to get all the lines that contain the DD being 04, how would I do this? I tried using grep "*-*04" but it didn't work.
Any quick one liners I should know about?

XINETD.LOG(5) File Formats Manual XINETD.LOG(5)NAME
xinetd.log - xinetd service log format
DESCRIPTION
A service configuration may specify various degrees of logging when attempts are made to access the service. When logging for a service is
enabled, xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix):
entry: service-id data
The data depends on the entry. Possible entry types include:
START generated when a server is started
EXIT generated when a server exits
FAIL generated when it is not possible to start a server
USERID generated if the USERID log option is used.
NOID generated if the USERID log option is used, and the IDONLY service flag is used, and the remote end does not identify
who is trying to access the service.
In the following, the information enclosed in brackets appears if the appropriate log option is used.
A START entry has the format:
START: service-id [pid=%d] [from=%d.%d.%d.%d]
An EXIT entry has the format:
EXIT: service-id [type=%d] [pid=%d] [duration=%d(sec)]
type can be either status or signal. The number is either the exit status or the signal that caused process termination.
A FAIL entry has the format:
FAIL: service-id reason [from=%d.%d.%d.%d]
Possible reasons are:
fork a certain number of consecutive fork attempts failed (this number is a configurable parameter)
time the time check failed
address the address check failed
service_limit the allowed number of server instances for this service would be exceeded
process_limit a limit on the number of forked processes was specified and it would be exceeded
A DATA entry has the format:
DATA: service-id data
The data logged depends on the service.
login remote_user=%s local_user=%s tty=%s
exec remote_user=%s verify=status command=%s
Possible status values:
ok the password was correct
failed the password was incorrect
baduser no such user
shell remote_user=%s local_user=%s command=%s
finger received string or EMPTY-LINE
A USERID entry has the format:
USERID: service-id text
The text is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response).
A NOID entry has the format:
NOID: service-id IP-address reason
