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

sieveshell

SIEVESHELL(1)						User Contributed Perl Documentation					     SIEVESHELL(1)

NAME

       sieveshell - remotely manipulate sieve scripts

SYNOPSIS

       sieveshell [--user=user] [--authname=authname] [--realm=realm] [--password=password] [--exec=script] [--execfile=file] server[:port]

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -p password, --password=password
	   The password to use when authenticating to server. Note that this parameter can be seen in the process list. Use with caution!

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.

       -f file, --execfile=file
	   Instead of working interactively, run commands from file file and exit when done.
