/* Coreutils 6.12 man page says:
|
|
* mktemp [OPTION]... [TEMPLATE]
|
|
* Create a temporary file or directory, safely, and print its name. If
|
|
* TEMPLATE is not specified, use tmp.XXXXXXXXXX.
|
|
* -d, --directory
|
|
* create a directory, not a file
|
|
* -q, --quiet
|
|
* suppress diagnostics about file/dir-creation failure
|
|
* -u, --dry-run
|
|
* do not create anything; merely print a name (unsafe)
|
|
* --tmpdir[=DIR]
|
|
* 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 even here, mktemp still creates only the final com-
|
|
* ponent.
|
|
* -p DIR use DIR as a prefix; implies -t [deprecated]
|
|
* -t interpret TEMPLATE as a single file name component, relative to
|
|
* a directory: $TMPDIR, if set; else the directory specified via
|
|
* -p; else /tmp [deprecated]
