What's ls option in OS X does what ls -w 1 in Linux does, showing output in one column? In Linux ls -w 1 shows list of files in 1 column instead of multi-column. What flag or other command will produce the same result in OS X?

Current output under OS X:

ls: 1: No such file or directory
The equivalent of the ls -w 1 command from Linux in OS X is: ls -1

From the man page for ls:


  -1 (The numeric digit “one”.) Force output to be one entry per line. This is  the default when output is not to a terminal.
