For cycle, process order
Hello,
I am running a script under ubuntu 16.04
I have no problem with the script. My question is general algorithm of for file command.
I just need to know how for file in *.txt process works.

Let's say, I wish to run the script by sorting filename:
Code:
for file in *.txt
do
"do something in alphabetical order"
done

or
Code:
for file in *.txt
do
"do something according to filesize in ascending direction"
done

or another way:
Code:
for file in *.txt
do
"do something in by recently updated file"
done

or
Code:
for file in *.txt
do
"do something by total string length of each filename in descending order"
done

In summarize: If we do not indicate any criteria, what's the default working method of for cycle ?
Thank you
Boris

torrus_monitor

TORRUS_MONITOR(8)						      torrus							 TORRUS_MONITOR(8)

NAME

       monitor - Torrus Monitor.

SYNOPSIS

       torrus monitor --tree=TREENAME [options...]

DESCRIPTION

       This command starts the Monitor process for the tree TREENAME. By default it forks into a daemon, sets the log output file to
       /var/log/torrus/monitor.TREENAME.log, performs one monitoring cycle, and sleeps until the next cycle is scheduled. In daemon mode the log
       file can be reopened by sending it a SIGHUP signal.

OPTIONS

       --nodaemon
	   Prevents the process from becoming a daemon and sets the log to STDERR.

       --runonce
	   Instructs the script to run once and exit. Implies --nodaemon.

       --delay=N
	   Makes the daemon sleep for N minutes before starting the first cycle.  This would happen on the daemon startup and also after each
	   configuration recompilation.  For example, when monitor and collector start simultaneously, the collector needs some time to retrieve
	   the data being monitored.

       --debug
	   Sets the log level to debug.

       --verbose
	   Sets the debug level to info.

       --help
	   Displays a help message.

FILES

       /etc/torrus/conf/torrus-siteconfig.pl
	   Torrus site configuration script.

       /var/log/torrus/monitor.TREENAME.log
	   Monitor's log for the tree TREENAME.
