redirecting STDOUT & STDERR

In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas?

I know that mmmmm 2> error.txt will send the error message to the specified file instead of the screen. However, I have seen >&2 in some scripts, and I can't get it to do anything. A source said it sends stdout and stderr to a file. What file? Ubuntu 18.04.2; Xfce 4.12.3;...

objZ(1) 						      General Commands Manual							   objZ(1)

NAME

       objZ - Compression utility

SYNOPSIS

       objZ [options] input

OPTIONS

       The  objZ  command  accepts  the following options: Decompress input.  The input file must be in ALPHAMAGICZ compressed object file format.
       Print the argument count, input length, and output length.

DESCRIPTION

       The objZ command takes a regular, read/write file in ALPHAMAGIC format as input and converts it to ALPHAMAGICZ compressed format. The  com-
       pressed output file replaces the input file.

       When  the  -u option is specified, the objZ command takes as input a file in ALPHAMAGICZ format (that is, a file previously produced by the
       objZ command or by the as command with the -compress option) and converts it to ALPHAMAGIC format.

ERRORS

       When compressing an input file, the objZ command generates errors if the file is not a regular file (for example,  a  directory	or  device
       special file), if the file is read-only, if its header cannot be read, if the file is not in ALPHAMAGIC format, or if a compression failure
       occurs.

       When decompressing an input file, the objZ command generates errors if the file is not a regular file, if the file  is  read-only,  if  the
       file is not in ALPHAMAGICZ format, or if a decompression failure occurs.
