How do I start a background process and save the process id to a file on my system. For example %wait 5 & will execute and print the process id. I can't figure out how to get it to a file. I've tried: > filename 0>filename 1>filename.

Thanks,

procset(4) Kernel Interfaces Manual procset(4)
NAME
procset.h - Send a signal to one or more processes
SYNOPSIS
typedef struct procset {
idop_t *p_op;
idtype_t p_lidtype;
id_t p_lid;
idtype_t p_ridtype;
id_t p_rid; } procset_t;
DESCRIPTION
The contents of the <procset.h> structure define a set of target processes based on logical operations performed on the two sets of poten-
tial target processes indicated by the two pairs of id + type parameters, which designate "left" and "right" groups of processes. The log-
ical operations supported are the union, intersection, difference, and exclusive OR of the left and right groups.
The p_lid and p_lidtype members define one set of potential target processes, the "left" set. The p_rid and p_ridtype members define the
"right" set of potential target processes. These parameters work together to select the target process or processes.
The value of p_op is used to combine these two groups into the final group of actual target processes: Specifies that the target group of
processes consist of the remaining processes in the left set that are not common to the right set. Specifies that the target group con-
sists of those processes that are in both sets. Specifies that the target group consists of those processes that are in either set, or in
both sets. Specifies that the target group consists of those processes that are in either set, but not in both sets.
