Shell Programming and Scripting

Well answer to this is simple..!
Whenever your second script will run , it will create a lock file, say "lckfile"
Before you add statements to your log file , in the main script, you just need to check if "lckfile" exists.

If it exists , it means you are archiving or chomping your original log files and you need to append your log statements in the temp log file.

If it does not exists, you are safe to add your log statements in the orignal log files.

Hope this helps!

The scenario here is different,fetchmail daemon is writing to logfile and in every 2 sec.I can't control the fetchmail daemon process once it starts running.So this is not applicable in the scenario.

This is what is specified in the man page for fetchmail.

"The --syslog option (keyword: set syslog) allows you to redirect status and error messages emitted to the syslog(3) system daemon if available. Messages are logged with an id of fetchmail, the facility LOG_MAIL, and priorities LOG_ERR, LOG_ALERT or LOG_INFO. This option is intended for logging status and error messages which indicate the status of the daemon and the results while fetching mail from the server(s). Error messages for command line options and parsing the .fetchmailrc file are still written to stderr, or to the specified log file. The --nosyslog option turns off use of syslog(3), assuming it's turned on in the ~/.fetchmailrc file, or that the -L or --logfile <file> option was used."

But I think you should go with option 1 , of restarting the daemon.

ok.I am looking into it.Thanks everybody for your time and comments
