hi... thanks for the reply to the shell question... my real issue is with trying to get java to run. i have a dir where "java" is a symbolic link to another symbolic link, which links to another.. when i type "./java" i get an error that indicates that it can't find a libjvm.so. i figured that i'd try to set JAVA_HOME, and LD_LIBRARY_PATH to see if that made/makes a difference.. it doesn't appear to.. anybody have any thoughts/suggestions on this.. i'm running a linux/redhat system, with the following... [root@bingo bin]# java -version java version "1.4.1" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1) Classic VM (build 1.4.1, J2RE 1.4.1 IBM build cxia321411-20040301 (JIT enabled: jitc)) thanks -bruce -----Original Message----- From: Wojciech Komornicki [mailto:wnk@xxxxxxxxxxx] Sent: Saturday, March 04, 2006 3:36 PM To: bedouglas@xxxxxxxxxxxxx; fedora-list@xxxxxxxxxx Subject: shell script/export question >>>>> "bruce" == bruce <bedouglas@xxxxxxxxxxxxx> writes: bruce:> hi.. bruce:> i have the following simple script... bruce:> # .foo bruce:> # User specific environment and startup programs bruce:> JAVA_HOME=/opt/IBMJava2-141 bruce:> export JAVA_HOME bruce:> ------------------- bruce:> when i do a >./foo.sh, and then do a echo $JAVA_HOME, i don't see the bruce:> exported variable. foo.sh has the exe bit set (777). any idea what i'm doing bruce:> wrong. i'm using fc4. i'm basically trying to figure out how to create a env bruce:> var, and export the var.

In the first instance you are setting and exporting the variable JAVA_HOME in the spawned shell. When that shell closes upon exit from foo.sh the evironment variable is lost. I the second instance you are setting the shell variable for the current shell. -- Wojciech Komornicki
