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]
