For loop/while condition - doubt
hi.,

As we know that using for-loop or while condition, we can only process one by one sequentially[according to provided input details], but , lets say this example :

1. under the folder "logs" there are 1000 files
2. each file has one record or line
3. have to perform atleast 7 queries per 3 seconds ,for instance
parse and process 7 files [each file has 1 record] in every three seconds

Can any one please share on how to do this shell or perl or python way.

postlog

POSTLOG(1)						      General Commands Manual							POSTLOG(1)

NAME

       postlog - Postfix-compatible logging utility

SYNOPSIS

       postlog [-iv] [-c config_dir] [-p priority] [-t tag] [text...]

DESCRIPTION

       The postlog(1) command implements a Postfix-compatible logging interface for use in, for example, shell scripts.

       By default, postlog(1) logs the text given on the command line as one record. If no text is specified on the command line, postlog(1) reads
       from standard input and logs each input line as one record.

       Logging is sent to syslogd(8); when the standard error stream is connected to a terminal, logging is sent there as well.

       The following options are implemented:

       -c config_dir
	      Read the main.cf configuration file in the named directory instead of the default configuration directory.

       -i     Include the process ID in the logging tag.

       -p priority (default: info)
	      Specifies the logging severity: info, warn, error, fatal, or panic. With Postfix 3.1 and later, the program will pause for 1  second
	      after reporting a fatal or panic condition, just like other Postfix programs.

       -t tag Specifies the logging tag, that is, the identifying name that appears at the beginning of each logging record. A default tag is used
	      when none is specified.

       -v     Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose.

ENVIRONMENT

       MAIL_CONFIG
	      Directory with the main.cf file.

CONFIGURATION PARAMETERS

       The following main.cf parameters are especially relevant to this program.

       The text below provides only a parameter summary. See postconf(5) for more details including examples.

       config_directory (see 'postconf -d' output)
	      The default location of the Postfix main.cf and master.cf configuration files.

       import_environment (see 'postconf -d' output)
	      The list of environment parameters that a privileged Postfix process will import from a non-Postfix parent  process,  or	name=value
	      environment overrides.

       syslog_facility (mail)
	      The syslog facility of Postfix logging.

       syslog_name (see 'postconf -d' output)
	      A prefix that is prepended to the process name in syslog records, so that, for example, "smtpd" becomes "prefix/smtpd".
