# Environment variables

mnoGoSearch understands a number of environment variables.

Table 9-1. Supported environment variables

Variable | Application | Purpose
UDM_CONF_DIR, UDM_ETC_DIR | indexer, search.cgi | Change the location of /etc directory. These two variables are synonyms. If both variables are set, then UDM_ETC_DIR is ignored.
UDM_TMP_DIR, TMPDIR | indexer, | Change the directory of the temporary files (e.g. created for external parsers) instead of the default /tmp. If both variables are set, then TMPDIR is ignored.
UDM_SHARE_DIR | indexer, search.cgi | Change the location of /share directory.
UDMSEARCH_TEMPLATE | search.cgi | Specifies the template file to use, instead of the default `etc/search.htm`. See also the Section called Using several templates in Chapter 8.
