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.
17 * create a directory, not a file
19 * suppress diagnostics about file/dir-creation failure
21 * do not create anything; merely print a name (unsafe)
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-
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]
