How long do temporary files made with mktemp last?
Temp files do not go away on their own. They are called temp
files simply because in your script or session or wherever you
are making them, you are expected to delete them when you are
done. Or leave them laying around if that's your thing. mktemp
exists solely to allow you to come up with a file that is named
something unique so that it doesn't overwrite some existing file.
description
Create a
temporary file or directory, safely, and print its name.
TEMPLATE must contain at least 3 consecutive
’X’s in last component. If TEMPLATE is not
specified, use tmp.XXXXXXXXXX, and
--tmpdir is implied. Files are created
u+rw, and directories u+rwx, minus umask restrictions.
-d, --directory
create a directory, not a
file
-u,
--dry-run
do not create anything; merely
print a name (unsafe)
-q,
--quiet
suppress diagnostics about
file/dir-creation failure
--suffix=SUFF
append SUFF to TEMPLATE. SUFF
must not contain slash. This option is implied if TEMPLATE
does not end in X.
--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 mktemp creates only the final component
-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]
