Requirement:
To move first 3 .log files to the "bak" directory.
The ways:
$ ls *.log | sed '1,3 !d' | xargs -i mv {} bak/
Same as
$ ls *.log | sed -n '1,3 p' | xargs -i mv {} bak/
Same as
$ ls *.log | head -3 | xargs -i mv {} bak/
Same as
$ ls *.log | head -3 | while read file
do
mv $file bak/
done
And using bash array:
$ FILES=(*.log)
$ mv "${FILES[@]:0:3}" bak/

Good One.
I really like the array's way , using substrings.
Sorry for the late comment. Just wanted to say thanks for showing the approach using Bash arrays.
Of course, in order to sort by anything but filename one would have to use e.g. FILES=($(ls -t *.log)) to sort by time.
