12 | /* 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] |
