docker exec CONTAINER_ID cat /home/siemplify_agent/.bash_profile > temp_bash_profile.txt
```
Run the following command to stop the agent's Docker container:
```
docker stop CONTAINER_ID
```
Run the following command to rename the container to create a backup:

Run the following command to copy the original contents of .bash_profile to the new container:

cat temp_bash_profile.txt | docker exec -i
    NEW_CONTAINER_ID sh -c 'cat > /home/siemplify_agent/.bash_profile'
