the out put is to short, how can i make the width longer?

Answer 1

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.

e.g.

strace -s 128 ...

Answer 2

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.

Answer 3

Use '-o filename' option:

  strace -f -o foo.log foo

man strace

-o filename Write the trace output to the file filename
