dtrace discuss - Jan 2007 - "dtrace -c" : how to redirect output

Hi,

Is it possible to redirect the output of the command specified as -c 
argument?
I.e. to do something like:
# dscript.d -c "date 1>out 2>err"

thanks in advance,
-katya

We don''t support shell expansions in the -c argument.  If you want to
do
the above, one easy way from ksh or bash is this:

dtrace -o /dev/fd/3 -s dscript.d -c date 3>&1 1>out 2>err 

which says:

dtrace''s stdout goes to fd 3, which is dup''d from the current
stdout
dtrace''s stderr goes to ''err''

date''s stdout is modified to ''out''
date''s stderr is modified to ''err''

Or you can use -o to specify a particular output file.
