To create the script open up a terminal window and use the contact command and create a clean file referred to as vault-server.sh.
contact vault-server.sh
After creating the vault-server.sh file, open it up in the Nano textual content editor.
nano -w vault-server.sh
Paste the code under into the Nano textual content editor.
#!/bin/bash
vault server -dev > ~/vault-server-info.txt
Save the edits with Ctrl + O, and exit with Ctrl + X. Then, replace the permissions of the file with the chmod command.
sudo chmod +x vault-server.sh
Accessing Vault
To entry Vault, open up a terminal window and execute the script file with the command under.
./vault-server.sh
