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

pwd(3tcl)						       Tcl Built-In Commands							 pwd(3tcl)

NAME
pwd - Return the absolute path of the current working directory SYNOPSIS
pwd _________________________________________________________________ DESCRIPTION
Returns the absolute path name of the current working directory. EXAMPLE
Sometimes it is useful to change to a known directory when running some external command using exec, but it is important to keep the appli- cation usually running in the directory that it was started in (unless the user specifies otherwise) since that minimizes user confusion. The way to do this is to save the current directory while the external command is being run: set tarFile [file normalize somefile.tar] set savedDir [pwd] cd /tmp exec tar -xf $tarFile cd $savedDir SEE ALSO
file(3tcl), cd(3tcl), glob(3tcl), filename(3tcl) KEYWORDS
working directory Tcl pwd(3tcl)
