    The "-s" option under Linux, from the "strace" package, will let you specify the width:

    -s strsize  Specify  the  maximum  string  size  to  print  (the
            default is 32).  Note that filenames are not consid-
            ered strings and are always printed in full.

  2. Use '-o filename' option:

      strace -f -o foo.log foo

    man strace

    -o filename Write the trace output to the file filename

  3. As other answers point to good directions in general, the specific issue is probably the space you have between "|" and "&". If you're trying to use a bash "|&" to pipe both stdout and stderr you can't have a space between those characters.
