# Chapter 12. Miscellaneous

# Environment variables

mnoGoSearch understands a number of environment variables.

Table 12-1. Environment variables mnoGoSearch understands

Variable | Application | Purpose
`UDM_CONF_DIR`, `UDM_ETC_DIR` | indexer, search.cgi | Changes the location of the `/etc` directory. These two variables are synonyms. If both variables are set, then `UDM_ETC_DIR` is ignored.
`UDM_TMP_DIR`, `TMPDIR` | indexer, | Changes the directory of the temporary files (e.g. created for external parsers) instead of the default location at `/tmp`. If both variables are set, then `TMPDIR` is ignored.
`UDM_SHARE_DIR` | indexer, search.cgi | Changes the location of the `/share` directory.
`UDMSEARCH_TEMPLATE` | search.cgi | Specifies the template file to use, instead of the default file at `etc/search.htm`. See also the Section called Using multiple templates in Chapter 10.
