       flip, toms, toix - do newline conversions between **IX and MS-DOS


       flip -h
       flip [ -umvtsbz] file ...
       flip [ -umvtsbz] -
       toix [ -vtsbz] file ...
       toms [ -vtsbz] file ...


       flip  is  a  file  interchange  program that converts text file formats
       between **ix and MS-DOS.  It converts lines ending with carriage-return
       (CR)  and  linefeed  (LF)  to  lines ending with just linefeed, or vice
       versa.  If the special argument "-" is given, input is read from  stdin
       and written to stdout.

       flip has the following features:

              flip  will  normally  refuse  to  convert binary files.  You can
              override this.

              When asked to convert a file to the same format that it  already
              has,  flip  causes  no  change to the file.  Thus to convert all
              files to **IX format you can type

                                  flip -u *

              and all files will end up right, regardless of whether they were
              in  MS-DOS  or in **IX format to begin with.  This also works in
              the opposite direction.

              If a file contains isolated CR  characters  for  underlining  or
              overprinting, flip does not change them.

              flip preserves file timestamps.  You can override this.

              flip preserves file permissions.

              flip is written in C and will compile and run under MS-DOS/Turbo
              C, 4.3BSD, and System V.

              flip accepts wildcards and multiple  filenames  on  the  command

              If  a  user  interrupt aborts flip, it does not leave behind any
              garbage files or cause corruption of the files being  converted.

              When  converting  from  MS-DOS  to **IX format, flip removes any
              trailing control Z (the last character in the file), but  leaves
              embedded  control  Z  characters  unchanged.  This minimizes the
              possibility  of  accidentally  converting  a  binary  file  that
              contains  a control Z near the beginning.  You can override this
              and ask flip to recognize the first control Z found  as  end-of-

              flip  can be asked to strip the high (parity) bit as it converts
              a file.

       flip is normally invoked as:
                      flip -umhvtb file ...
       One of -u, -m, or -h is required.  Switches may be given separately  or
       combined  together  after a dash.  For example, the three command lines
       given below are equivalent:
                      flip -uvt *.c
                      flip -u -v -t *.c
                      flip -u -vt *.c

       On systems that allow a program to know  its  own  name,  flip  may  be
       renamed  (or  linked)  to  a  file  called  toix for conversion to **IX
       format, or to a file called toms for conversion to MS-DOS format.  When
       invoked with the name toix or toms, flip will act as if it were invoked
       with the -u or -m option respectively.


       -u     Convert to **IX format (CR LF => LF, lone CR  or  LF  unchanged,
              trailing control Z removed, embedded control Z unchanged).

       -m     Convert  to MS-DOS format (lone LF => CR LF, lone CR unchanged).

       -h     Give a help message.

       -v     Be verbose, print filenames as they are processed.

       -t     Touch files (don’t preserve timestamps).

       -s     Strip high bit.

       -b     Convert binary files too (else binary files are left unchanged).

       -z     Truncate file at first control Z encountered.
