Find Program's Home

To find out where an application is installed is:

$ whereis adobe-flashplugin
adobe-flashplugin: /usr/lib/adobe-flashplugin

Also, another useful command to determine file type:

$ file /usr/lib/adobe-flashplugin/libflashplayer.so
/usr/lib/adobe-flashplugin/libflashplayer.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped
