How to use the Linux mktemp command

A temporary file created by mktemp for use by shell scripts.

Syntax

Instance

When you use the mktemp command to generate a temporary file, the file name parameter should be given in the form of "file name. XXXX". mktemp will create a temporary file based on the file name parameter. Enter the following command at the command line prompt:

Mktemp tmp. xxxx # generate a temporary file

After using this command, you can use dir or ls to view the current directory and get the following results:

Cmd @ cmd-desktop :~ $ Mktemp tmp. xxxx # generate a temporary file cmd @ cmd-desktop :~ $ Dir # view the current directory file test testfile testfile1 tmp.3847 # tmp.3847 is generated

The generated temporary file is tmp.3847, where "XXXX" in the file name parameter is replaced by four randomly generated characters.
