getting wrong output with AWK command!!!
i have a file which gets appended with 9 records daily and the file keeps growing from then...i use to store the previous day files count in a variable called oldfilecount and current files count as newfilecount.my requirement is that i need to start processing only the new records from the file....i mean only if newffilecount > oldfilecount and only fetch the current days 9 records and process it...the no of records which is 9 as of now might vary later..so i just need to fetch the records which has come for today neglecting all the previous days records and process the current records alone...
i tried
awk 'NR>$oldfilecount {print $0}' $eachfile | sed 's/"//g' > outfile
but i m getting all the records displayed...even the old records :-(
but when i give
awk 'NR>64 {print $0}' $eachfile | sed 's/"//g' > outfile i get only the current days records...
How do i get my job done...since the oldfilecount variable keeps changing and based on that i need to filter out the old records and fetch only the new records and process it...
Thanks in advance!

runacct(1M) runacct(1M)
NAME
runacct - run daily accounting
SYNOPSIS
[mmdd[state]]
DESCRIPTION
runacct is the main daily accounting shell procedure. It is normally initiated via cron(1M). runacct processes connect, fee, disk, and
process accounting files. It also prepares summary files for prdaily or billing purposes.
runacct takes care not to damage active accounting files or summary files in the event of errors. It records its progress by writing
descriptive diagnostic messages into When an error is detected, a message is written to mail (see mail(1), mailx(1), or elm(1)) is sent to
and and runacct terminates. runacct uses a series of lock files to protect against re-invocation. The files and are used to prevent
simultaneous invocation, and is used to prevent more than one invocation per day.
runacct breaks its processing into separate, restartable states using to remember the last state completed. It accomplishes this by writ-
ing the state name into runacct then looks in to see what it has done and to determine what to process next. states are executed in the
following order:
Move active accounting files into working files.
Verify integrity of
file, correcting date changes if necessary.
Produce connect session records in
format.
Convert process accounting records into
format.
Merge the connect and process accounting records.
Convert output of
chargefee into format and merge with connect and process accounting records.
Merge disk accounting records with connect, process, and fee accounting
records.
Merge the daily total accounting records in
with the summary total accounting records in
Produce command summaries.
Any installation-dependent accounting programs can be
included here.
Cleanup temporary files and exit.
To restart runacct after a failure, first check the file for diagnostics, then fix up any corrupted data files such as or The files and
file must be removed before runacct can be restarted. The argument mmdd is necessary if runacct is being restarted, and specifies the
month and day for which runacct will rerun the accounting. Entry point for processing is based on the contents of to override this,
include the desired state on the command line to designate where processing should begin.
EXAMPLES
To start runacct.
To restart runacct.
To restart runacct at a specific state.
WARNINGS
Normally it is not a good idea to restart runacct in its state. Run manually, then restart via:
If runacct failed in its state, remove the last file because it will not be complete.
