How do I list only files in Linux?

Here are some additional options that I find useful and interesting:

1. List only the . txt files in the directory: ls *. txt.
2. List by file size: ls -s.
3. Sort by time and date: ls -d.
4. Sort by extension: ls -X.
5. Sort by file size: ls -S.
6. Long format with file size: ls -ls.
7. List only the . txt files in a directory: ls *. txt.
