[plug] unusual commands

[smclevie]

Hi

I'm a little baffled with the following:

$ export PATH=/opt/sun/bin:/usr/local/bin:/usr/local/sbin: 
/usr/local/openssl/bin:/usr/sbin:/usr/bin:/usr/ccs/bin: 
/usr/openwin/bin:/usr/dt/bin:/usr/platform/SUNW,Ultra-Enterprise/sbin: 
/opt/SUNWexplo/bin
$ export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/ssl/lib: 
/usr/local/openssl/lib:/usr/ccs/lib:/usr/openwin/lib: 
/usr/local/lib/perl5/5.8.2/sun4-solaris/CORE

I believe it is something related to an environment variable called 
LD_LIBRARY_PATH.

How does one know if it is 'set'? OR its setting??

Thanks,

Steve
