, but
each line will end with the carriage-return character
^M.When you are using Interix, there are a few things you should
know about UNIX and Windows text-file formats. For instance, when
you create a text file using a Windows text editor, such as Notepad
or MS-DOS Edit, each press of the ENTER key inserts two characters:
a carriage-return character and a line-feed character. Text editors
that run on POSIX systems only use a line-feed character to mark
the end of a line. You can open a Windows text file in vi(1), but
each line will end with the carriage-return character
^M.
Most Interix utilities require their scripts to be in POSIX
format. This means that the end of a line of text can be marked
with only a line-feed character. Some programs, however, such as
ksh(1),
make(1), and
awk(1) with
the -f option, will run scripts in either POSIX or Windows
text format.
The flip(1)
utility converts carriage-return/line-feed character combinations
into a line-feed character and vice versa. The flip -u
command converts a text file into the POSIX text format. The
flip -m command converts a text file into the Windows/MS-DOS
text format. For example, flip -u memo converts the file
called memo into POSIX text format.
