create a temporary file or directory


Create an empty temporary file and return the absolute path to it

$ mktemp

Create a temporary directory and return the absolute path to it

$ mktemp -d

Create a temporary file with a specified suffix

$ mktemp --suffix "[.txt]"


mktemp [ OPTION ]...[ TEMPLATE ]


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]

--help display this help and exit

--version output version information and exit
