reading a file for processing
i have file which looks like this:
Code:
file=/var/log/log1.log
file=/var/log/log2.log
cmd=ls -l
cmd=dir > /var/log/mylog.log

now i have to write a script which will read all "file" tag values and copy them and read all "cmd" values and run them etc..

what i was thinking to do is:
read file by line and:
1. use awk or sed to get file value process or run cmd if cmd value.

problem with this aproach is while i am copying file i am blocked and cant process further so if any file copy or cmd takes more time i cant process further.

so i thought of using another approach:
i will process above file and create a array of files and cmds and then i can process them individually.

I am new to shell scripting, so creating array and processing i have to read about.
please suggest me right way if you can define better.

i can also consider changing my above file sturcture if you have better way of copying files and processing cmds written there.

Thanks, Ajay

doveadm-log

DOVEADM-LOG(1)							      Dovecot							    DOVEADM-LOG(1)

NAME

       doveadm-log - Locate, test or reopen Dovecot's log files

SYNOPSIS

       doveadm [-Dv] log errors
       doveadm [-Dv] log find [directory]
       doveadm [-Dv] log reopen
       doveadm [-Dv] log test

DESCRIPTION

       The  doveadm  log commands are used to locate and reopen the log files of dovecot(1).  It's also possible to test the configured targets of
       the *log_path settings.

OPTIONS

       Global doveadm(1) options:

       -D     Enables verbosity and debug messages.

       -v     Enables verbosity, including progress counter.

COMMANDS

   log errors
       doveadm log errors

       The log errors command is used to show the last	- up to 1,000 - errors and warnings.  If no output is generated, no errors  have  occurred
       since the last start.

   log find
       doveadm log find [directory]

       The  log  find  command	is used to show the location of the log files, to which dovecot(1) sends its log messages.  If dovecot(1) logs its
       messages through syslogd(8) and doveadm(1) could not find any log files, you can specify the directory where your syslogd  writes  its  log
       files.

   log reopen
       doveadm log reopen

       This command causes doveadm to reopen all log files, configured in the log_path, info_log_path and debug_log_path settings.  These settings
       are configured in /etc/dovecot/conf.d/10-logging.conf.
       This is for example useful after manually rotating the log files.

   log test
       doveadm log test

       This command causes doveadm to write the message "This is Dovecot's priority log (timestamp)" to the configured log files.  The used prior-
       ities are: debug, info, warning, error and fatal.

EXAMPLE

       This example shows how to locate the log files used by dovecot(1).

       doveadm log find
       Looking for log files from /var/log
       Debug: /var/log/dovecot.debug
       Info: /var/log/mail.log
       Warning: /var/log/mail.log
       Error: /var/log/mail.log
       Fatal: /var/log/mail.log

REPORTING BUGS

       Report  bugs,  including doveconf -n output, to the Dovecot Mailing List <dovecot@dovecot.org>.	Information about reporting bugs is avail-
       able at: http://dovecot.org/bugreport.html
