Why will reading in a an environment variable and opening a file "a" (append) not work?
The file pointer will be at the end of the file?

Instead of explaining what you think should be done, please tell us your requirements.
There is some kind of misunderstanding about how file descriptors work going on here.

NAME
autrace - a program similar to strace SYNOPSIS
autrace program [-r] [program-args]... DESCRIPTION
autrace is a program that will add the audit rules to trace a process similar to strace. It will then execute the program passing arguments to it. The resulting audit information will be in the audit logs if the audit daemon is running or syslog. This command deletes all audit rules prior to executing the target program and after executing it. As a safety precaution, it will not run unless all rules are deleted with auditctl prior to use. OPTIONS
-r Limit syscalls collected to ones needed for analyzing resource usage. This could help people doing threat modeling. This saves space in logs. EXAMPLES
The following illustrates a typical session: autrace /bin/ls /tmp ausearch --start recent -p 2442 -i and for resource usage mode: autrace -r /bin/ls ausearch --start recent -p 2450 --raw | aureport --file --summary ausearch --start recent -p 2450 --raw | aureport --host --summary SEE ALSO
ausearch(8), auditctl(8). AUTHOR
