compare two files
I have two files.
one file consists of process ID's:
ProcessID1
ProcessID2
ProcessID3

Second file consists of 3 records:
username1 ProcessID1 Date1 Time1 ProcessName1
username2 ProcessID2 Date2 Time2 ProcessName2
username3 ProcessID3 Date3 Time3 ProcessName3

I have to search the first file whether any of the process id's of second file are present or not
If process ID is not there in the first file corresponding to second file, then we will move that record to a new file, otherwise we will remove that record.
I have written a script for this.But it is not working.

script:
for file in second_file
do

cut -c 8-12 second_file>>dummy_file

if [ dummy_file == First_file ]
$file >>new_file
else
continue
done

can anybody help me in this?

Thanks in advance

runacct

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.
