mmapfiles_example.txt [plain text]
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

^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

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,
