| 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]
