ddev: Run a specific command within a container.
$ ddev exec ${echo 1}
try on your machine
The command ddev exec ${echo 1}
is using the ddev
command line tool to execute a command within a Docker container.
Here's a breakdown of the command:
ddev
: Refers to theddev
command line tool, which is typically used for local development with web-based projects.exec
: Specifies that the command given after it should be executed within a running Docker container associated with the project.${echo 1}
: This part is using variable substitution in the command to execute the result of the commandecho 1
. Theecho
command is used to print the string passed to it as an argument, and in this case, it is1
.
So, when ddev exec ${echo 1}
is executed, it runs the command echo 1
within the Docker container and outputs 1
as a result.

never run a command you are not sure if it is safe.
