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
