12 niro 816 /* Coreutils 6.12 man page says:
13     * mktemp [OPTION]... [TEMPLATE]
14     * Create a temporary file or directory, safely, and print its name. If
15     * TEMPLATE is not specified, use tmp.XXXXXXXXXX.
16     * -d, --directory
17     * create a directory, not a file
18     * -q, --quiet
19     * suppress diagnostics about file/dir-creation failure
20     * -u, --dry-run
21     * do not create anything; merely print a name (unsafe)
22     * --tmpdir[=DIR]
23     * interpret TEMPLATE relative to DIR. If DIR is not specified,
24     * use $TMPDIR if set, else /tmp. With this option, TEMPLATE must
25     * not be an absolute name. Unlike with -t, TEMPLATE may contain
26     * slashes, but even here, mktemp still creates only the final com-
27     * ponent.
28     * -p DIR use DIR as a prefix; implies -t [deprecated]
29     * -t interpret TEMPLATE as a single file name component, relative to
30     * a directory: $TMPDIR, if set; else the directory specified via
31     * -p; else /tmp [deprecated]
