That would be stupid. Error messages belong on stderr, that's why it exists.


This is done because when running a batch of commands with the output
sent
to a file, logs collected are not shown chronologically because the
output
is split between stdout and stderr.  (...)


There are two obvious fixes:
1) don't send batches of commands that ignore errors, so that the processing immediately stops at the failed entry. 2) change the error message text to include the input line number where it failed. 

Also a possibility:
don't send running status messages to stdout, send them only to stderr. Technically the only commandline tool that normally produces "output" is ldapsearch. Everything else is "diagnostic" and belongs on stderr anyway. 


  I suggest instead a -B option to make stdout unbuffered or
  linebuffered.


stdout is already linebuffered by default when directed to a tty.
