Method 1 Use the mktemp or tempfile utility to create temporary random file name As the name suggests, both following commands create a unique temporary file or directory. This will generate a random string of length 20 that only includes uppercase letters and digits. I need to generate many random alphanumeric strings, which also use capital letters. For example, to generate a random string of length 20, you can use the following command: In bash script, how to generate a random string. You can adjust the length of the random string by changing the number passed to the -base64 option. This will generate a random string of length 10 that only includes uppercase letters and digits.
