After having saved the Clish Configuration with the "save configuration config.

You will find the config.txt file in the home directory of your user account (e.g. /home/admin/)1. The save configuration config.txt command is a Clish command that saves the current Gaia configuration to a text file2. The file is stored in the home directory of the user who executed the command, and it can be accessed by using the cat or less commands in expert mode1. The file can also be transferred to another machine by using the scp or sftp commands1. The config.txt file contains the Clish commands that are needed to restore the Gaia configuration to the same state as when the file was saved2. The file can be used for backup, migration, or troubleshooting purposes2.
