Is there a standard method to add to ENV variables conditionally on being empty?`?

If the code above is copied and pasted, then the answer is trivial.

If the code above is copied and pasted, then the answer is trivial. Spell LD_LIBRARY_PATH Consistently (The occurrence of LD_LIB_PATH is probably not what you had in mind. ) When tested using: sh -x mysetup.Sh (. .

/mysetup. Sh; sh -x mysetup.Sh) (unset LD_LIBRARY_PATH; sh -x mysetup. Sh) I saw that $AXIS2C_HOME/lib was added by the first command, and that it was not added twice by the second command sequence, and that the third command sequence just set it.

An alternative mechanism is to use a script such as clnpath documented in How to keep from duplicating path variable in csh, or one of the other answers there. Basically, they analyze a path-like variable and ensure it contains no duplicates.

DOH! It is painful to work on HP, AIX, NCR, and Linux all in one day. Thanks Jonathan!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
