LRZIP=NOCONFIG environment variable setting can be used to bypass lrzip.conf. LRZIP=NOCONFIG environment variable setting can be used to bypass lrzip.conf.
TMP environment variable will be used for storage of temporary files when needed. TMP environment variable will be used for storage of temporary files when needed.
TMPDIR may also be stored in lrzip.conf file. TMPDIR may also be stored in lrzip.conf file.
If no filenames or "-" is specified, stdin/out will be used (stdin/out is
inefficient with lrzip and not recommended usage). If no filenames or "-" is specified, stdin/out will be used.
