ok, thank you for the replies... I now understand export.. It's essentially making a variable global... Now my question is, in my bashrc I have:
What is the purpose of exporting these variables? What is referencing MANPATH, INFOPATH, MAGICK_HOME, DYLD_LIBRARY_PATH? Are these necessary to have? the test -r line.. I know that is something that my fink installer added-- so I guess I want that, but what does that mean exactly?
Quote:
umask: set default file permissions for new created files&directories; umask 002 means your default file permission is 664, and 775 for directories.
.. Ok-- so, if I don't have this umask 0002 line, what would my permissions be set to? Is it standard to have this line in your bashrc, and is 0002 the best thing to have it set to?
thank you very much for the help and explanations.

lint
lint(1B) SunOS/BSD Compatibility Package Commands lint(1B)NAME
lint - C program verifier
SYNOPSIS
/usr/ucb/lint [options]
DESCRIPTION
/usr/ucb/lint is the interface to the BSD Compatibility Package C program verifier. It is a script that looks for the link
/usr/ccs/bin/ucblint to the C program verifier. /usr/ccs/bin/ucblint is available only with the SPROcc package, whose default location is
/opt/SUNWspro. /usr/ucb/lint is identical to /usr/ccs/bin/ucblint, except that BSD headers are used and BSD libraries are linked before
base libraries. The /opt/SUNWspro/man/man1/lint.1 man page is available only with the SPROcc package.
OPTIONS
/usr/ucb/lint accepts the same options as /usr/ccs/bin/ucblint, with the following exceptions:
-Idir Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The
directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files
in the directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and
finally, in /usr/include.
-Ldir Add dir to the list of directories searched for libraries by /usr/ccs/bin/ucblint. This option is passed to
/usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib.
-Y P, dir Change the default directory used for finding libraries.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/usr/lint/bin/ld link editor
/usr/lib/libc C library
/usr/ucbinclude BSD Compatibility directory for header files
/usr/ucblib BSD Compatibility directory for libraries
/usr/ucblib/libucb BSD Compatibility C library
/usr/lib/libsocket library containing socket routines
/usr/lib/libnsl library containing network functions
/usr/lib/libelf library containing routines to process ELF object files
/usr/lib/libaio library containing asynchronous I/O routines
