Mktemp

Internal

• Linux

Overview

mktemp takes file name templates and overwrites portions to generate a unique file name, creates the empty file with 0600 permissions (only the current users can read and write) and displays the file name at stdout. If no template is given, a unique file name appropriate to the system will be generated and the empty file is created. On Mac, mktemp creates something similar to /var/folders/t3/mmn20npx7fs31lwlp2s4_6wm0000gq/T/tmp.hbvowAQL. Create a uniquely named temporary file or directory and display its name at stdout.

local f
f=$(mktemp) || exit 1

The file such created is NOT removed automatically, it is the user's responsibility to remove it.

Options

-d

Create a temporary directory instead of a file.

 mktemp -d
