-# Looking
-

-
-> apropos unzip
-

-
-> dpkg -l
-
-List what's installed.
-
-# Libraries
-
-Libraries under /lib/ typically contain an .so suffix when they're dynamic.  It means 'shared object' as a number of programs will refer to it.
-
-Others will have an /a/ suffix, meaning that they're static, and will be loaded at runtime.
-
-We can check the dependencies of a program using the ldd command upon anything in a library. For example:
-
-> ldd/usr/bin/md5sum
-
-... shows us that md5sum depends upon:
-
-- linux-vdso.so.1
-
-- libc.so.6
-
-- lib64/ld-linux-x86-64.so.2
-
-To list all libraries, run:
-
-> ldconfig -p
-
-For example, if looking at /usr/lib/x86_64-linux-gnu/libXcomposite.so.1, we might wonder what it's for.  We can then run:
-
-> ldconfig -p | grep libXcomposite
-
-... and find out nothing except that it redirects /usr/lib/x86...
-
-So at least we know where it is.
-
-> ldconfig -p | grep usb
-
-... this will show where things which nominally relate to usbs live.
-
-You can add to the libarary path by putting just any text file in /etc/ld.so.cache, e.g. in Arch where the path to the fakeroot environment is placed there.
