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.

    And with colors: strace $CMD 2>&1 > /dev/null | vim -c ':set syntax=strace' -. – Pablo A Aug 27 '17 at 14:43

Use '-o filename' option:

  strace -f -o foo.log foo

man strace

-o filename Write the trace output to the file filename

    True, not directly an answer, but I found it useful in this context nonetheless. It does write the full strings into the file. – user63623 Jan 12 '17 at 15:49
  • Not really, @user63623. I've tried it here and ended up having to use -s anyway (strace 4.26). – hdiogenes Jun 3 at 22:13
