maybe you should choose another filename for the
output file, other than the name of the input file...
actually you are overwriting the input file.

insert here:  filelist=`ls -1 *.txt
and replace the following line with
for fname in filelist ; do also add here:
set out                # just to close the last produced file, otherwise you may
never see it
