UNIX for Dummies Questions & Answers

I want to add paths to a CLASSPATH variable but if I use the :

setenv CLASSPATH /opt

all previous entries are erased. How do I append additional entries to a system variable without overwriting the original value.

Thanx

try setenv $CLASSPATH:/opt

You might also want to consider ...

export CLASSPATH=$CLASSPATH:/opt

this will add /opt to the END of the classpath - i.e. will look in this directory last ....
ALTERNATIVELY

export CLASSPATH=/opt:$CLASSPATH

This will add /opt at the front of the classpath. This will then look here first....can be important if the target file appears in multiple parts of the path....and the files differ - you need to make sure the one you are wanting is earlier in the classpath.

Thats' great.

Thanks for your help
