BAM flags using "OR"

[RockChalkJayhawk]

I'm trying to extract all reads where both are mapped (but not necessarily in the proper orientation/size) and remove PCR duplicates.
I tried

samtools view  -F 8 -F 4 -F 1024 $BAM

but I think it is interpreting as -F 1036 (which is not what I want). Is there any way around this?

Thanks in advance.

Eazy fix:

samtools view  -h -f1 -F 4 $BAM|samtools view -S  -F 8 -|samtools view -S -F  1024
