ls command

Hi, I have a question for a course I'm taking which I cant find the answer to:

Suppose you wanted to display their contents of testdir exactly like this?

testdir/bahenSW.JPG testdir/nothing.txt testdir/xxx
testdir/blucrest.jpg testdir/text.txt

I've tried all the ls command flags and none of them display the file listings of a directory like this. What am I missing?

Like this?

# mkdir testdir 
# cd testdir
# touch bahenSW.JPG nothing.txt xxx blucrest.jpg test.txt
# cd ../
# ls testdir/*
testdir/bahenSW.JPG   testdir/nothing.txt   testdir/xxx
testdir/blucrest.jpg  testdir/test.txt

very good,thank you

Thank you

ah yes tyvm
