The following is a demonstration of the mmapfiles.d script.

Here we run mmapfiles.d while in another window a new bash shell is started.
The files that were mapped in aren't suprising, they are the common shared
librarios,

   # mmapfiles.d
   Tracing... Hit Ctrl-C to end.
   ^C
   MMAPS CMD              PATHNAME
       1 bash             /lib/libdl.so.1
       3 bash             /lib/libsocket.so.1
       3 bash             /lib/libnsl.so.1
       3 bash             /lib/libc.so.1
       3 bash             /lib/libcurses.so.1



Now we examine zsh. This time a number of extra libraries are mapped,

   # mmapfiles.d
   Tracing... Hit Ctrl-C to end.
   ^C
   MMAPS CMD              PATHNAME
       1 zsh              /lib/libdl.so.1
       3 getent           /lib/libc.so.1
       3 getent           /lib/libnsl.so.1
       3 getent           /lib/libsocket.so.1
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/parameter.so
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/zutil.so
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/complete.so
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/stat.so
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/zle.so
       3 tset             /lib/libc.so.1
       3 tset             /opt/sfw/lib/libncurses.so.5.2
       3 zsh              /lib/libc.so.1
       3 zsh              /lib/libm.so.2
       3 zsh              /lib/libcurses.so.1
       3 zsh              /lib/libnsl.so.1
       3 zsh              /usr/sfw/lib/zsh/4.2.1/zsh/complist.so
       3 zsh              /lib/libsocket.so.1



Sometimes the output can be quite suprising. The following shows the mmaps
caused by the "sdtaudiocontrol" tool, a java tool to change the volume levels
on Solaris,
