NIS_PATH Environment Variable

You can change or augment the list of directories NIS+ searches through by changing the value of the environment variable NIS_PATH. NIS_PATH accepts a list of directory names separated by colons:

setenv NIS_PATH directory1: directory2: directory3 ...

or

NIS_PATH=directory1: directory2: directory3 ...;export NIS_PATH

NIS+ searches through these directories from left to right. For example:

Like $PATH and $MANPATH, the NIS_PATH variable accepts the special symbol, $. You can append the $ symbol to a directory name or add it by itself. If you append it to a directory name, NIS+ appends the default directory to that name. For example:

If you use the $ sign by itself (for example, org_dir.$:$), NIS+ performs the standard name expansion described earlier: it starts looking in the default directory and proceeds through the parent directories. In other words, the default value of NIS_PATH is $,

Keep in mind that additions and changes to your NIS_PATH may increase the number of lookups that NIS+ has to perform and thus slow down performance.
