tail not working on mac terminal

Due to my lack of experience with script language, (shame for a Mac user) I have referred to several sources: link seemed resolved with ls *.extension | xargs -n 1 tail -n +2 This didn't for me, even after adding > merged.txt at the end, nor the following: for f in *.txt do tail -n +2 $f >> /path/to/some/dir/with/files/file_name done I also tried sed -e'1d' $FILE in replacement of the tail command. Didn't work. tail -n +2 file_name.extension, cat LIN_1994-11_0100.txt | tail -n +2, awk 'FNR != 1' *.extension has no effect to the file. I am uncertain if this has anything to do with the current issue. Or whether the link is related to the issue. If anyone could find the reason for this problem or way out of it..would be majorly grateful. I have transferred this issue from another community here to receive more insight if I could.
