An alternate approach could be with: ./test_script.sh
Code:
#!/bin/bash
list_dir="." 
# list_dir is set to current pwd, 
# as you have shown your *txt files reside in the same pwd as your script...
# this actualy means, the 'cd $list_dir;' part would not be required, 
# but this would let you get the plain file names, rather than with the full path.
for filename in $(cd "$list_dir";ls *.txt | head -n4 )
do      echo "$filename"
done

Have fun
