NAME

       bup-newliner - make sure progress messages don't overlap with output

SYNOPSIS

       <any command> 2>&1 | bup newliner

DESCRIPTION

       bup newliner is run automatically by bup.  You shouldn't need it unless you're using it in
       some other program.

       Progress messages emitted by bup (and some other tools)  are  of  the  form  "Message  ###
       content\r",  that  is, a status message containing a variable-length number, followed by a
       carriage return character and no newline.  If these messages are printed more  than  once,
       they   overwrite   each   other,   so  what  the  user  sees  is  a  single  line  with  a
       continually-updating number.

       This works fine until some other message is printed.  For example, progress  messages  are
       usually  printed  to  stderr,  but  other program messages might be printed to stdout.  If
       those messages are shorter than the progress message line, the screen will  be  left  with
       weird looking artifacts as the two messages get mixed together.

       bup newliner  prints  extra  space  characters at the right time to make sure that doesn't
       happen.

       If you're running a program that has problems with these artifacts, you  can  usually  fix
       them by piping its stdout and its stderr through bup newliner.
