In my current directory, I execute the command:
ls -1 and it gives a list of the current directory contents.
In the same directory, I repeat the command:
ls and it gives me the same result, with perhaps a different formatted output.
Finally, I try to find out about the available commands by typing
ls --help and the output is:
usage: ls [-ABCFGHLOPRSTUWabcdefghiklmnopqrstuwx1] [file ...]
It looks like the last option is
1 (#1). Can someone explain what the
ls -1 does and how it's different to the standard
