mktemp

create a temporary file or directory

TLDR

Create an empty temporary file and print its absolute path

$ mktemp
copy


Use a custom directory if $TMPDIR is not set (the default is platform-dependent, but usually /tmp)
$ mktemp -p [/path/to/tempdir]
copy


Use a custom path template (Xs are replaced with random alphanumeric characters)
$ mktemp [/tmp/example.XXXXXXXX]
copy


Use a custom file name template
$ mktemp -t [example.XXXXXXXX]
copy


Create an empty temporary directory and print its absolute path
$ mktemp -d
copy

SYNOPSIS

mktemp [OPTION]... [TEMPLATE]

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 a slash. This option is implied if TEMPLATE does not end in X

-p DIR, --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

-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]
