| 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] | ||
