"ls"

This command used to see what files you have. Your files are kept in something called a directory.
% ls
test test1
test2 test3
pantas pantas2
%
Note that you have six files. There are some useful variants of the ls command:
% ls t*
test test1 test2 test3
%
Note what happened: all the files whose name begins with "l" are listed. The asterisk (*) is the "wildcard" character. It matches any string.
