Create a temporary file or directory, safely, and print its name.
TEMPLATE must contain at least 3 consecutive `X's in last component.
If TEMPLATE is not specified, use tmp.XXXXXXXXXX, and --tmpdir is implied.
create a directory, not a file
do not create anything; merely print a name (unsafe)
suppress diagnostics about file/dir-creation failure
append SUFF to TEMPLATE. SUFF must not contain slash.
This option is implied if TEMPLATE does not end in X.
interpret TEMPLATE relative to DIR. If DIR is not
specified, use $TMPDIR if set, else /tmp. With
this option, TEMPLATE must not be an absolute name.
Unlike with -t, TEMPLATE may contain slashes, but
mktemp creates only the final component
use DIR as a prefix; implies -t [deprecated]
interpret TEMPLATE as a single file name component,
relative to a directory: $TMPDIR, if set; else the
directory specified via -p; else /tmp [deprecated]
