989# strace -elseek <pdv archive>
990# basically look for the first lseek command (we do the strings/grep because
991# sometimes the function call is _llseek or something) and steal the 2nd
992# parameter. here is an example:
993# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
994# lseek
995# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
