An example of use:

2. List files for all subdirectories: #ls-r//The last instruction only lists all directories and files in this directory, but the files under the directory are not listed in the loop.
3. What if the file is too large to see? And, about the name of a file you want to find in many files.
3.1 split screen display: #ls-l|more//Can be at the time of the screen exit, very useful, but not a page by page flip screen
#ls-l|less//can turn the page with PGUP,PGDW, but cannot exit at that time
